C# and games

Hey /prog/! 5 questions for you.

1. What is C# used for except Xbox games?
2. What is a good programming language for writing games that run on windows...
3... and on other OS's.
4. Good prgramming language for writing windows apps...
5... and for other OS's?

1. It's used for many scales, each of minor, major and other tonalities.
2. VBA is good. Oh, and Excel has a few neat games.
3. I'm sorry, only Windows runs games. /g/ will tell you that right away.
4. VBA again. Or, if you're really nerdy, apparently there's a framework called DOTNET or something. I dunno, look it up.
5. Linux is written in C and Mac programs aren't written in any language I know of.
