Well, there is wine (http://winehq.com) but it's still a little glitchy (I got it to work with Dream Maker, once after I fooled around with it, it worked pretty good, untill you went to edit icons, then it crashed, but heck, it's better than nothing.)
If about 50% of the games I have moved to linux, I would run linux 90% more.
I'm going to go, and say it is not better!. Yes thats right. The upside to linux is that people that use it know what they are doing. While the vast majortory of windows users are compleatey clueless about how a computer works.</font>
