Computer Gaming is bad?

Computer games don't work for me. My sis has a game for my computer and it always freezes and runs slow. Not saying the one on xbox is any better because it isn't :P but I have bad luck with computer games

Your situation prob isn't the game depending on the game type, how populated the area is (Multiplayer) and such.

But generally, if you have a decent gaming computer, good grahpics card and such, you shouldn't run into these problems.
