C, of course. Sepples in an abomination of a clusterfuck of a poor excuse for a language.
>>15 is right in that Windows game programmers often use it, but that's for two reasons:
1. Windows doesn't have a canonical C compiler. MSVC is a Sepples toy.
2. People who take up programming to become game programmers are usually dim.
If you intend to make a career out of writing games (and don't intend to do it by yourself like
MDickie), you'll probably want to pick up Sepples at some point, but it's a terrible, terrible choice for a beginner.
Also keep in mind that most established game programming libraries (including Allegro and SDL) are written in C.
