Call-of-Duty- | wireless controller for shooting games | Game Engine library

It just depends on the game. For triple A games, I woukd say most of it is binary data like texture, models, media (like video, cinematic, audio). Then you have the way your game is packed and lot of dependencies like C Redistribuable, game engines, physics engine, libraries, etc ... While many of those are not used they may still be packed in the game. For some "indie" games like Minecraft, I wouldn't be surprise code is what take most of the space (or Audio I guess ?). Note that the map can be larger than the game too ... What you can do is use a tool like Windirstats to check what is happening, but It will not find dependencies that are out of the folder.

For the codebase, I guess its mainly automated through games engines.

Here is an example for Conan Exile :

So it's mainly texture data (GraniteSDK), the game engine files is 115MB and executable are 100MB (note that it has Battleye anti-cheat packed, + the server version of the game). Video is 500MO ...

Another example for Minecraft :

Which is (contrary to what I expected) mainly texture/sound data.

What about, let's say, Chrome ? Interpretation : I have no clue :D.

Last one: Python itself is not quite big. But all the dependencies, their dependencies (the dlls, etc) are quite big at the end.
