Names are important. Besides art style, they are people's first point of contact with your game. Names set expectations, and used well can capture the imagination. People will use it to answer "is this game for me?" Microsoft Flight Simulator is going to attract a different set of people than No Man's Sky, though groups may be equally excited about the prospect of their chosen game. A good name should be seamlessly integrated into the core fantasy/setting/story/experience your game offers (along with art, music, narrative style).
That's not to say you can't have fun or need to have corporate board meetings over it (I doubt the AaaaaAAaaaAAAaaAAAAaAAAAA!!! designers were particularly meticulous, for example), choosing a name is not a design decision to be ignored. Also, it's hard to start publicizing a game before it has a name (and you should be publicizing it as soon as you have anything to show), which is exactly what I'm running up against for my neural circuit game.
So, one of my first steps in any design decision is to look at what's already out there. Here's a collection of games I've compiled (through other research or just pulled off the front page of Steam) and tried to organize into thematic and functional piles. This isn't meant to be a thorough and strict classification -- I only am trying to better understand different approaches and functions of naming games.
(full disclosure: the ones with links are from people I know)
Exactly What It Says On The Tin
Kerbal Space Program
Artemis Spaceship Bridge Simulator
Species: Artificial Life, Real Evolution
Golf With Your Friends
Keep Talking And Nobody Explodes
Learn Japanese To Survive
American Truck Simulator
Very straightforward, people know *exactly* what their experience will be. Almost all are (or at least started out as) indie games where there’s more leeway for more artistic names like these.
Monsters Ate My Birthday Cake isn’t an explicit instruction to the player like some of the others, but it is super efficient while being fun. It includes protagonists, items, and actions: you control monsters to obtain birthday cake.
A main thing in the game (that you do?)
Offworld Trading Company
The Deadly Tower Of Monsters
Ceres Tactical Space Combat
Ark: Survival Evolved
Age Of Empires
Left 4 Dead
Game Dev Tycoon
The Last Leviathan
Closely related to simple descriptions. Good at establishing the central theme of the game without too much fluff.
I almost put Vermintide in the made-up words category -- it’s a good example of being poetic but still delivering what’s in the game (i.e. fighting hordes of rats), especially with the Warhammer main title.
The name of my own game, Starship Rubicon, isn't amazing. It tells you that there's spaceships involved, but Rubicon doesn't do anything besides act as a kinda-unique word. The name implies some kind of irreversible decision, but the game has more of a series of small interesting decisions than one or two large dramatic ones.
Life Is Strange
Single or phrase that maybe doesn’t tell you exactly what’s in the game but establishes the aesthetic.
XO is cool because it also means "commanding officer", which is exactly the role you play in it. However, such a short name means they have a hard time with SEO and have had some trouble with sites not supporting two-letter projects.
Many sound like yogurt advertisements while conventionally beautiful women do yoga. Extra points if it ends with an A. Better if it tells you something about the game? For example, Xenobloom tells me that alien plants are going to be involved, while Balrum doesn't do anything on its own. It's debateable, though: Bioshock tells me nothing (and is actually kind of misleading?) but it’s more memorable than Eufloria (which involves new types of life). Though that example may just be due to the larger marketing budget.
Apparently EITR is from a substance from within the game, but I think it’s still unfamiliar enough a word to be in this category.
No Man’s Sky
Kentucky Route Zero
Crypt Of The Necrodancer
Homeworld: Deserts Of Kharak
My favorite set of names, I think. Tend to be incredibly poetic while still delivering a lot of information about the game. I can’t tell if I think the names are incredible or just most of the games here are fantastic in themselves.
This category is great especially when it implies action. No Man's Sky? Better fly around in it! Darkest Dungeon? I bet I’m gonna delve that. Sunless Sea is a place where you are scared while boating around. Kentucky Route Zero is a thing you’re gonna travel down.
"The Story Of”
Chronicles Of Teddy
The Stanley Parable
Valdis Story: Abyssal City
All memorable, work to tell me a little about the game. Best when the entry they choose out of the thesaurus entry for 'story' is thematically relevant: Banner Saga is literally a Viking saga but Valdis Story looks to be actually more of a fighting game (?).
The protagonist(s) // thing of importance
Company Of Heroes
The Elder Scrolls: <place>
Styx Master Of Shadows
Thea The Awakening
Ryse Son Of Rome
Hyper Light Drifter
Children Of Morta
Pillars Of Eternity
The Witness (?)
Child Of Light
Mighty No 9
Almost all the triple-AAA franchises ended up here. I guess this category is general enough to allow for sequels in the same universe + characters.
Also has a number of one-off smaller games (Broforce, Bastion/Transistor, Children of Morta, Mushroom 11, Hyper Light Drifter). I recall that Shovel Knight actually ran into a hiccup when they wanted to release an expansion with a different main character. They ended up just adding a “plague of shadows” subtitle.
I hope this is helpful to some of you! My takeaway is that it's best to laser-focus in on the core experience your of your game and to try and convey or imply that. Easier said than done, of course.
