Yesterday I picked up Star Wars Knights of the Old Republic on Steam for $2.50. I installed it and checked it out last night. Surprisingly enough, it worked flawlessly on Windows 7/64. The highest resolution it will support is 1600×1200, which looks pretty good.I had to use Creative ALchemy to re-enable EAX in the game, since Windows 7 only likes OpenAL.
I played for a while and was reminded just how much fun I had playing the game years ago. Bioware really knows how to make good RPGs.
