3d accelaration support is kind of limited in Linux; you should remember that not too many firms make 3d games for Linux (some do), and there haven't been quite at all 3d-accelarated games around except lately (Linux itself isn't that old yet). In the future this could change, but it takes time. Windows is the leading 3d-accelarated-games-running OS, and stays that way for a while it seems..as long as the 3d-card manufacturers don't start writing good, easy-to-install drivers that are updated as necessary (these days I know only ATI and nVidia make somewhat good drivers).
I'd suggest you try out the MESA project. Use the Google, Luke.
EDIT: I don't know if any distribution gives you hardware 3d-accelaration by default; and if some do, then you probably need to have a very well known ATI or nVidia gfx card. I'd let these Playstations, Xboxes and Nintendoes do the gaming stuff and leave computers do the other things..after all, computers create a whole lot of trouble when it comes to games, and are slow and sluggish because they need to run many other things too besides the games.
