As you might know Outcast 2 and Delta Force 3 will be polygon based/hardware accelerated.
I loved to play Outcast; seems like you don't see the pixels anymore after some time of playing. http://discussions.hardwarecentral.com/smile.gif
The best positional 3D sound is in Thief and Thief II, even on just two speakers.
I'll be back...
