Bitsy (http://ledoux.io/bitsy/editor.html): is a simple browser based game editor that doesn't need any coding or even logic. The tool itself has predefined types of sprites and actions. The user needs only to draw different images and define dialogues for each game character, connect everything together, and TADAAAAAA, you finished a simple html game. All games created by it are topdown story based games where the player can talk to different objects.

Dungeon Decorator (https://lorenschmidt.itch.io/dungeon-decorator): is similar to Bitsy, except it designs platformers. The user needs to design the map, some dialogues, and they have a game. All games created by the tool are platformer story based games where the player can talk to different objects.

Twine (http://twinery.org/): is one of the most famous interactive story tools. You can design your text based adventure game, interactive stories, and etc. Twine is a very easy to use tool where you build a story branching tree and link it together. Twine exports html and javascript games, so adding any javascript code works fine in the game. Here are some known games made with Twine:

ChoiceScript (https://www.choiceofgames.com/make-your-own-games/choicescript-intro/): same as the previous tool in creating interactive stories. The output game is played in different way than games developed by Twine. Examples of games done with it:

Ink (http://www.inklestudios.com/ink/): same as the previous tools in creating the same genre. One of the features of Ink is its can be easily integrated in Unity (will talk about it later). Examples of games done with it:

Inform (http://inform7.com/): is similar to Twine where it is used to create interactive stories or text adventure games.

Adventure Game Studio (http://www.adventuregamestudio.co.uk/): used to create point click adventure games like Monkey Island. I didn't use this tool for a very long time, but I remember how easy it was to design a game using it. Here are some examples of games designed by it:

RPG in a Box (http://www.rpginabox.com/): is a game engine to create topdown voxel based RPG/Adventure games. The tool use logic trees to add the logic and game flow, but you can write the code yourself if you want. Examples of games created by this tool:

RPG Maker (http://www.rpgmakerweb.com/): is a game engine powered by Ruby/JavaScript. This engine helps you design Japanese RPG games easily. It has many functionalities that can help you make a game without writing any line of code, but to do more complex stuff, you need to learn a little bit of Ruby/Javascript. Examples of games done using it:

PuzzleScript! (http://www.puzzlescript.net/): is a scripting engine where you write a few lines of scripts (that you can learn in less than 1 hour) to have puzzle games similar to Sokoban. PuzzleScript is powerful language that you can use it to script lots of different type/genres of games using it (not just puzzle games). The output games are light weighted html5 games. Examples of games created:

Construct 2 (https://www.scirra.com/): is a game engine that is designed to generate cross platform games using web technologies. The engine doesn't need any coding and is easy to learn. This tool is famous between non programmers. Examples of games done using it:

Stencyl (http://www.stencyl.com/): is a HaXe based game engine. The tool allows you to write code, but if you want to code, you can do almost all the functionalities using logic trees. Most of the famous games by Stencyl are for mobiles, but it works well with any other target. Examples:

Game Maker Studio (http://www.yoyogames.com/): is one of my favorite tools. This was the first game engine I ever used, and I think is the first known game engine before all this engines got out. I used it when I was a kid and didn't know how to program. Game Maker allows you to use drag and drop to do all the logic for your game, but it also give you the ability to write code for it using its own scripting language (GML). Examples of games done using game maker:

Clickteam Multimedia Fusion 2.5 (http://www.clickteam.com/): I remember trying this tool when I was a kid. It is really great and many amazing games have been developed using it. This tool doesn't need any coding skills, as it is a drag and drop tool like Game Maker. Examples of Games:

GDevelop (http://compilgames.net/) is an open source tool, and as simple as Construct 2. It follows the same philosophy too. The only problem is it is not as popular as Construct. Example of games:

Gamesalad (http://gamesalad.com/) is one of the old game engines. It is old, few people use it and, from their website, it appears they target more schools and teaching institutes than indies and developers. This tool is similar to Stencyl in the way you develop games. You don't need coding, just logic trees and you are fine. Example of games done with it:

GameBuilder Studio (http://gamebuilderstudio.com/): is a game engine that use the same philosophy behind Unity, but with no coding (just logic trees). I didn't use it much, but it seems nice. This engine is not popular so I couldn’t find famous games developed using it.

Buildbox (https://www.buildbox.com/) is a component based game engine like Unity, but with no coding skills required. It seems like a new engine, but the company developing it is pushing a lot of money for indies to start picking it up and develoing their games. You can see competitions from time to time with huge prizes. Examples of games done using it:

Voxatron (http://www.lexaloffle.com/voxatron.php) is a fantasy console made by an indie developer. The main idea behind it is to create 3d voxel based games and shared them with other people online (as the games are all HTML). I didn't use it, but it seems simple and easy to use. It might need some programming skills, but not much. Example of games:

Pico-8 (http://www.lexaloffle.com/pico-8.php): is a fantasy console by the same developer behind Voxatron, but this is famous between indies. Lots of indies make Pico-8 games. You need to know a little bit of programming to create games in Pico-8. Pico-8 create HTML games in form of sharable cartridges. All games are 8 bit games with a fixed screen size and use same buttons. Example of games by Pico-8:

PixelVison 8 (https://pixelvision8.itch.io/game-creator): is similar to Pico-8. Games are written in Lua. The difference is that this game engine is not as famous as Pico-8. I couldn't find any well known games using it.

Unity (https://unity3d.com/): is one of the most known game engine. Personally, I don't like it. The problem is it has terrible support for 2D games, and is confusing to use for beginners. Its easy to deploy on any device. It has a huge community supporting it. Any new game technology takes Unity developers into account. To use it, you need to have some coding skills either C# or JavaScript. Many famous games are developed using it. Examples of these games:

Unreal Engine (https://www.unrealengine.com/what-is-unreal-engine-4): is another famous engine. Unreal focus more on performance and graphics than other functionalities. But it is always simple to extend the functionality of the engine by writing some scripts. Here is a list of games developed by it:

Cryengine (https://www.cryengine.com/): is another famous engine. Cryengine is similar to Unreal in focusing on performance and graphics. Here is a list of games developed by it:

Cocos Creator (http://www.cocos2d-x.org/): is similar to unity in the interface and how to use it. It's used to create 2D games as it uses Cocos2D-X. Examples of games using it (Cocos2D-X):

MightyEditor (http://mightyfingers.com/): is an open source game editor for Phaser. It allows designing scenes with sprites/images and modify them. The game logic has to be programmed in Javascript. I couldn't find any known games designed using it.

Phaser Editor (http://phasereditor.boniatillo.com/): is similar to MightyEditor as both of them are editors. Phaser Editor IDE is an update over eclipse so if you are used to eclipse, you won't have huge problem with interacting with Phaser Editor. I couldn't find any known games designed using it.

Superpowers (http://superpowers-html5.com/index.en.html): is an open source game engine similar to unity but powered by TypeScript. The output games are HTML and Javascript. Its not that famous but the main ideology behind it, is to have this nice ecosystem in working together with your team on a project together. List of games developed by it:

Godot (https://godotengine.org/) is our last engine in the list. This engine is very similar to Unity, and even needs coding skills, the only difference is that it is open source. It is not popular, so I don't recommended this much, but it could suit somebody out there. Here a list of games created using it:
