Terra Incognita
I just tried it out and I must say this is one very groovy game. The game is suprisingly smooth considering it's software driven (doesn't get to touch the nice graphic hardware stuff), an example of software and hardware could be for like anyone who's played Half Life, the moment you switched from Software(strictly your system) to Open GL(using the video card) and the sound is so so.
Shame there isn't any basic save option, as the intro is rather lengthy if you want to go straight to action.
