People who program games for fun

Do you have a game engine that you use/are developing?

Did you get it from a book/uni/scratch/industry?

do you have a void.h you bring into your applications?

Also Windows/Linux/Xbox/BSD/Other/Mac?

I like playing free software Linux games. I mostly do low hanging fruit bug fixes and usually publish my fixes to the public domain. I mimic the predominant style of the project. On my own projects, I just do GNU style. I target general Posix systems whenever possible, I don't really care if shit breaks for Windows.
