siplus, the fact that you can run win32 applications at all on a non windows system is a bonus. try running a linux program on windows and see how far you get.
As for games, they are just as important on linux as any other platform, it's just that the webmaster's opinion (and he is a mac user by the way) is that if you want to play games, then buy a playstation, and there's a lot to be said for that.
also, linux is just as compatible as windows, and in many cases is even more so, however if you are dead set on running windows programs rather than alternatives, then you will probably have to keep using windows. otherwise, just install your red hat, and a lot of the free programs that come with it, and try them all out!
