If yes, which distro do you suggest? And why?

They are all pretty much the same, but there's a specific distro that has some pretty good games preloaded. http://www.games-knoppix.org/

They're fixing some bug with the latest version, so come back in a few days to download the latest version, or if you just wana experiment with it, you may also download one of the older versions which are pretty good as well. I used V5.0, and it had a lot of games.

i think windows is better.many games are programed to using in the windows.in other OS it maybe work not very well.

WINE does allow some Windows games to run under Linux, but its hardly ideal. If you're wanting to play commercial games, then I'd suggest sticking with Windows. If you're happy to play open source alternatives, then Linux has lots of options, but for people who want to play what their friends are playing, Windows is better.

Ah, i have never heard of that distro, a friend of mine uses linux system loaded with the new Fedora 6, so i think i may give this distro a try, if it goes well then i am gonna use Linux for my system. Thanks for helping out.
