I’m not entirely new to game programming, I have some experience with Unity3D and Flash (FlashPunk in FlashDevelop). I know there are many other Flash Libraries out there (like AS3ISOLIB), but I’d like to know what engine or library I should use for my next game. What I’m trying to make is a first-person game (so I need 3D), but with a low resolution, a bit like a 90’s game. The tricky part, however, is that I’d want to manipulate files and folders, for example making the game close by itself, and automatically create a text file, open a folder, or open a text file/image. Is this possible in Unity? Or should I do it in another engine?
