The
story of Operation Flashpoint's development is quite unusual in
the game industry these days. For one thing, the team didn't start out
as professionals; originally only the lead programmer was allowed to work
on the game full-time. Switching publishers three times, starting a new
company, growing the team from one to 12 full-time members, and moving
offices five times during the game's development were just some of the
hurdles we had to clear. Only the team's vision and obsession for the
game remained consistent from the very first playable version until the
end. It's not possible to describe whole story in the space given for
this article, so let's just jump directly to the final moments.
It was 8
p.m. on Friday, May 25, 2001. Our publisher's representative, who had
been in Prague for the last few days to make sure everything was going
O.K. as we were finalizing the gold master, left Prague feeling confident
that things were going well — the disc was almost ready and could
be sent to final testing and then to manufacturing after some weekend
testing.
Meanwhile,
our lead programmer (to make matters even more exciting, he was then working
at his temporary home in France for couple of weeks) was trying to resolve
some serious graphical anomalies with the hardware transformation and
lighting (HW T&L) rendering. If he were to fail, HW T&L would
not be included in the final release. If he solved it, some data organization
changes would be necessary to suit the needs of the HW T&L. He spent
nearly the whole day resolving some random crashes that appeared in the
game during the last day, going back and forth over e-mail with an Nvidia
support engineer. The crash was fixed by late afternoon, and by 10 p.m.
it looked like the HW T&L problems were at an acceptable level. Around
midnight, the tools that would perform the data format change were ready.
e-mail with the lead programmer (while also trying to implement new localized
string tables and fix some problems in the campaign and missions). At
3 a.m. it looked like all the data had been converted — and both
the lead programmer and the team leader could go have some sleep.
Saturday
morning, our publisher realized that the gold master hadn't actually been
delivered. Tensions rose even further, and nerves began to unravel. Only
two days remained before mass production was scheduled to begin. Everyone
on the team had been working since early Saturday morning, but at times
a successful end to these last-minute crises seemed to be so far away.
By around 5 p.m. on Saturday, most of the important issues in the code
had been resolved, and the lead programmer decided to take another look
at the HW T&L implementation. Luckily, within a few hours, he suddenly
discovered the root of all of the HW T&L problems and fixed them.
The plan was to deliver the gold master to our publisher via FTP by that
evening. Nobody expected that it would actually take until Sunday morning.
After a long, sleepless night of playing through the game and fixing any
problems that appeared, everything looked fine, and most of the team could
finally go to sleep again.

Operation Flashpoint's mission was to deliver the tension of full-scale conventional military conflict. |
With some relief, we finally started the game upload on Sunday around 9H But were we done? Not yet. Suddenly, a seagull stopped flying in some of the in-game cutscenes. The team leader called to wake up the lead programmer in France: "The seagull is not flying. What should I do?" We had to stop the upload until the lead programmer delivered necessary code fix. After the project leader received the updated files from the lead programmer, he started to rebuild the game in Visual Studio. It was Sunday around noon, and the game had finally gone to the publisher for final testing.
The publisher's
test staff started playing the game Sunday afternoon. Everything went
smoothly at first, but later they discovered one serious scripting bug
in one of the campaign missions that made it unplayable. Late in the evening,
they called the team leader about the bug, and he had to drive to the
office after sleeping just a couple of hours over the past three days
to fix the bug as quickly as possible and then upload the fixed version
to the publisher's server in the U.K. Around midnight Sunday night, the
disc was finally ready to go.
Three weeks later, hundreds of thousands of copies of the game were available in stores worldwide. In the meantime, the development team was playing the game, terrified of finding a disastrous bug. Fortunately, no such critical bug appeared. Considering the amount of work we'd done on the game in those last couple of days and hours, the risk of finding some major problems was pretty high. On Friday, June 22, the game was released, and it immediately became the top-selling PC game in many countries. The team knew that their mission was successfully completed. The passion and hard work of every single member of the development and publishing teams started to pay off.
What Went Right
1.The
team. Probably the most positive thing we encountered during development
of this game was the people working on it. Almost all of the people who
joined the team really helped to improve the game and remained fully dedicated
to it from the first day until the final moments. While we were understaffed
almost all the time, we are happy to say that while the team was growing
steadily, it was very stable — almost all the people who participated
in the development of Operation Flashpoint are still working at
our studios now that the game is finished. Another advantage was that
the team was very cooperative. Some roles on the team were not demarcated
very strictly. Still, between the programmers, designers, and artists,
everyone could comment on any part of the game, and everyone's opinions
were taken seriously.
While this often made communication more difficult, it definitely helped the design and development process and enriched the game in many areas. One of the most powerful tools we used for internal communication was our intranet news server, which proved to be an invaluable tool during the whole design process. The game was mostly designed on the fly, and the newsgroups made the design process not only convenient, but really quite enjoyable.
2.The
community. Operation Flashpoint's public following is incredible.
We ourselves are surprised by the number of people creating fan sites,
developing new content for the game, or just keeping in touch with the
community by reading news and forums. Currently there are hundreds of
different sites dedicated to Flashpoint, and dozens of them are of a truly
professional quality with news updated almost hourly.
Another great thing about the community is that some of the people have been following this game for years already, and they still carry a great deal of enthusiasm for it. Some of the first great fan sites started out more than two years before the game was released, and we managed to keep people's excitement going with regular updates about the improvements we were making to the game throughout its development. We take it as a good sign that most of the sites are still online and updated regularly. About halfway through development, we invited some people from the community to participate in the design of the game directly, via external forums and newsgroups. Their skills in both military and gaming areas were invaluable, and we constantly used their feedback to improve the game.
Since the
release of the public demo version (around three months prior to the release
of the final game), the community following has become much bigger. The
only downside to the increase in the community base is that the community
has become much less focused and less mature, as the average age of those
visiting the web sites has descended notably.
But the community still looks really vital and the most-visited fan site
has counted millions of page views already. Recently, fans have been creating
many custom-made tools and enhancements to the game in addition to the
various web sites and services.

3.Open
architecture. Since we know that plenty of players enjoy not just
playing games but also providing their own content for them, we wanted
to enable this extensibility as much as possible. Therefore, the game
included exactly the same mission editor that we had used to design our
missions. In addition, much of the game's functionality is data-driven
instead of being hard-coded. This includes not only the mission files
and world maps but also the capabilities and properties of units. The
units are stored in a very powerful hierarchical configuration tree with
inheritance capability, yet they are relatively easy to edit. By using
these configuration files, it is possible to add completely new units
and worlds to the game or add modified versions of existing ones, which
is what many players are doing to create their own content, thus lengthening
the product's lifespan. We wanted to use configuration files to shorten
coding time as well, because we figured that the fine-tuning of most values
could be done by designers or testers instead of programmers. But this
didn't work as we expected, mostly because only the programmers really
knew meaning of the values.
Our scripting
language also featured highly in the game's development and extensibility.
We started to build the mission editor as a visual tool, but we soon recognized
its limitations in certain areas. Seeing this, we added an expression
evaluator for trigger activation, which was surprisingly powerful, and
a full scripting language soon followed. When the game was released, we
knew immediately that scripting was a really good choice, as many user-made
mission used scripts to implement specific new functionality. Looking
back, we can say scripting proved to be much more powerful than we expected.
We only wish we had added it sooner in the development cycle, so that
some of the functionality that we hard-coded into the game could have
been scripted instead, including some AI behavior.
At a later stage of development (after the European release, in fact), we extended the game's ability to support add-on content. Single files stored in specific folders could add, for instance, new models, units, or islands. Besides some official add-ons that we have introduced since the game's release, there is already a massive number of user-made add-ons, all available for free on the Internet.

4. Creative
freedom. From the very beginning of the project, we tried to create
the game that we really wanted to play. We didn't look too much toward
other games for inspiration, and we virtually ignored games that might
be considered our competition. We also gave little regard to whether the
market would like the game or not. Our relationships with publishers were
never too strong (actually, we changed publishers several times), and
all important decisions were made by the core development team, keeping
us relatively independent throughout the game's development. In fact,
changing publishers so many times wasn't strictly a negative thing. Even
though it led to some financial uncertainties, the creative freedom we
enjoyed instead of some more money was more than worth it.
The result
of this creative freedom is a game that is really distinct. Our design-on-the-fly
approach (or "design by playing," as we prefer to think of it)
made the game very enjoyable and a different experience from any other.
Most design decisions were first discussed (mostly in newsgroups as mentioned
earlier) and then tried out in the game. No matter how nice a design idea
might have seemed at first, only the elements that worked well in the
game ended up being included.
5. Long
development cycle. The unusually long time that Flashpoint was in
development was very beneficial. In terms of gameplay, the game is very
mature, which would not have been possible in a shorter development cycle,
especially because this was our first major game. Two or three years into
development, the game started to be really enjoyable. In fact, it was
polished enough then to suit our original plans for the release version.
But due to various things (mainly on the publishing side), the game wasn't
released at that point, which gave us more time to polish and improve
it. We were able to incorporate various features that we originally hadn't
planned to develop, either because they were too difficult or required
excessive CPU or memory resources.
We were also able to incorporate feedback from various external testers — our friends as well as colleagues at well-known gaming companies who evaluated the game throughout its development. We refocused and redesigned the game a couple of times, always opting to keep everything that worked well and change the things we felt could work better.
What Went Wrong
1.Development
cycle much longer than expected. Ironic as it is, we have to start
What Went Wrong exactly where we left off with What Went Right. Despite
some of the usefulness the extra development time offered us, in the end
th cycle was probably too long, and in optimal conditions would have been
at least 20 percent shorter. It may have been possible to shorten the
cycle, but we experienced various external events or internal missteps
that prevented us from accomplishing that.
First of
all, some technologies in the game were a bit outdated after more than
four years. We didn't know at the outset that the game would be still
in development after so long, and we hadn't left time at the end to rework
parts of the engine. Some of the criticism of Operation Flashpoint
addresses the amount of detail in the textures and some models —
and we have to admit that these could have been better.
Furthermore, the excessively long development cycle led to burnout and heavy exhaustion, particularly for the people who had been working on the game since very beginning (the lead programmer, lead artist Jan Hovora, and the team leader). In some cases, we weren't able to sustain some of the features we'd implemented two or more years prior. They just disappeared somehow in the process of reworking parts of the code, and we didn't even notice. Newcomers to the development and testing process never knew such features had ever existed.
The main problem wasn't that the development cycle was too long per se, but that the development was so much longer than we'd expected. Next time, we will work much more diligently to better estimate our development time — and we will probably try to aim higher with the detail of our artwork, even if it seems insanely detailed for present and predicted hardware capabilities.

2.Documentation.
Lack of documentation is a common affliction among game developers, but
some aspects of this problem were so severe in our case that they are
worth mentioning.
While we'd never believed too much in designing the game on paper, the
real problem was that we never even had documentation of the things that
we'd finished. This situation led to incredible problems in the final
stages of development. Many tasks could only be done by one person on
the whole team. In other cases, hours were spent trying to investigate
how something had originally been meant to work. We recognized these problems
and tried to improve them, but apart from a few instances, our effort
wasn't really successful.
As the development team grew, the missing documentation was becoming a more serious problem. But the final project deadlines were getting closer as well, so it was nearly impossible to find the time to address the problem.
3. Quality
assurance. We experienced various problems in communication and cooperation
with our publisher. Generally, their focus and assistance in some areas
of the production of the game (design suggestions, voice-overs, translation,
scriptwriting) were really helpful. But in other areas, we experienced
some events and circumstances that slowed down and complicated the game's
development rather than moving things forward.
One of the
most unsatisfactory areas was the way the QA procedures were managed and
designed to work by the publisher. We never succeeded in achieving a common
bug database, and the publisher enjoyed an illusory feeling that its QA
database really covered the project. The truth was that such a database
(even without any direct access for the development team) hardly said
anything about the project's status because it covered just small fraction
of all the problems we had tried to fix. Even when the publisher dedicated
a pretty big testing team to the game, it sometimes seemed something of
a waste of time for everyone involved in it.
In the end,
we had to largely ignore the publisher's QA reports, because they contained
too much useless information and very few real bugs. We tried to focus
on very limited external testing managed directly in the very late stages
of development to ameliorate this problem — but this approach could
hardly replace real, full-time testing of the game.
We admit the situation was very difficult for the QA team as well — in no small part because of the lack of documentation on our side — but we still believe this process could have been handled much better. One of the mistakes we made was assuming that the publisher's QA would be sufficient, so we didn't build a strong testing team in-house. We definitely will find a solution for any future projects, because the way it was done for Operation Flashpoint wasn't satisfactory.

4. Some
content was not under our full control. One very concerning thing
was that our final CD was still manipulated by the publisher. The publisher
applied SafeDisc protection to the final code, which caused some unexpected
compatibility problems that we weren't able to control. The mixing of
various SafeDisc versions and a serious compatibility problem with Windows
2000 that was present in the first European batch of CDs could have been
avoided.
In addition,
we weren't able to finalize the English language in the game because we
didn't have a native English writer on the team. We also didn't oversee
the voice recording and voice actor selection, which led to some results
that were unsatisfactory to us.
5. Multiplayer
API. From the very beginning we were aware that our game had huge
multiplayer potential, especially if it were implemented as a massively
multiplayer online game. But we knew we would be unable to deliver such
experience. Instead of aiming for such an unrealistically high goal, we
decided to implement mission-based multiplayer that shared as much code
as possible with single-player game. Even this effort proved to be extremely
difficult. Operation Flashpoint was always developed primarily
as single-player game with a strong story, but for a very long time we
were thinking about multiplayer functionality, and we tried to design
the game code in such a way that it would help us incorporate multiplayer
later.
For implementation,
we wanted to avoid low-level network coding and instead use a high-level
API. As we were already using Direct3D for graphics and DirectSound for
audio, and both suited our needs quite well, we decided to use DirectPlay
as our network API. DirectPlay offered high-level handling of all network
communication, including Voice Over Net capabilities. Unfortunately, our
experience with this API was extremely bad. Often when trying to get some
high-level functionality working, we realized it contained bugs that rendered
it almost unusable.
We had to
implement our custom code for things we thought DirectPlay would provide,
but that was sometimes very hard, as we did not have the low-level control
that we needed. We also encountered many performance problems, some very
strange, such as significant (particularly server-side) slowdown even
with no traffic over the network. This along with the lack of documentation
and alack of stability resulted in many problems that were hard to debug.
Another
drawback that we didn't recognize beforehand is that DirectPlay is Windows-only,
but many dedicated servers for games currently being played online run
on Linux. Overall, selecting DirectPlay as our network API was one of
the most unfortunate decisions in the whole game's development.
Future Dreaming
Most start-up
game developers dream of developing a number-one title. We weren't any
different. With Operation Flashpoint, this dream has come true
for us. The game achieved the number-one position in sales charts of various
countries and regions, including the U.S., Germany, the United Kingdom,
Benelux, Scandinavia, and Australia. More than 500,000 copies sold worldwide
in just three months, proving to us that our last four years of effort
were worth something.
We always stayed focused on the game, and we didn't have too much regard for those who believe that the success of any game is mainly a question of marketing, securing a big license, or working on a sequel. We always believed that it's the game itself that makes the difference between success and failure.

The combination of infantry with full simulation of vehicles is a crucial part of the design of Operation Flashpoint. |
We're still
playing the game and we still like it. After such a long time, it's hard
to believe that Operation Flashpoint remains the favorite choice
of games for most of the development team. We're still working on new
content for Flashpoint out of pure enthusiasm. In the end, we don't feel
ourselves to be anything more than proud members of a big and healthy
Flashpoint fan community that has arisen around the world.
We know that someday we will have to leave Flashpoint to its own destiny. But currently, we still feel too involved in the game. We are already looking forward to future projects, but it will take months for us to start one. We consider the success of Operation Flashpoint as the pole position for our next race. We plan to use all the experience and resources that we have gained during the last couple of years to push gaming even further in the future.
