and of course there are also commercial games that support Linux like Doom3/Quake4
also, if Sof2 officially supports linux, you can google "Sof2 linux installer" and you might find a .run file that will help you get everything up and running. Or at least, that is how it worked for me when I installed Quake3/Quake4/Doom3.
*sigh* maybe if we are really lucky then Blizzard will decide to throw in a linux port of StarCraft 2 After all, why should the Mac users be getting more love than the Linux users?
Yeah, that may very well be the grim truth. However, I have, along with a couple of other people, expressed interest on the Battle.net forums in a native Linux version of StarCraft 2. Hopefully they will see at the very least that there is some interest in this and with a lot of luck (and maybe a miracle) they will decide to port it.
