SWBF2 seems to be incompatible with vista so even if I got it, I couldn't play it. What kind of game is it anyways? rts?
Quick summary:
It's a 1st/3rd person shooter in the vein of BF2. Large maps, capture points, classes, 2 sides, vehicles, etc. Also features space maps where you can dogfight in x-wings, tie fighters, droid fighters, and other ships, or you can grab a transport and board the enemy capital ship. Playing well on maps can get you temporary access to heroes/villains. For example, on Coruscant you can access either Mace Windu or Darth Maul.
I googled around about with Vista issue. Some folks have the game running fine, others have problems. A common issue seems to be RealTek soundcard related, though a fix has been discovered. When I got my dual-core X2 CPU, I had to set the .exe to Win98 compatibility mode for the game to work, but since then it has been perfect. Here are some relevant links:
