Bourne is the most interesting one so far; it keeps pace with the very fast feeling of the movie, keeping you on your toes at all times. The fighting system is completely bad a**. It is a very simple, yet effective system and it looks great, with a lot of special movies. The graphics are good, not great, but the demo is very fun.
Haze has great graphics, IMO, on par with Uncharted. It looks a little like a cross between Halo and Turok though. The controls are easy enough to pick up and game play is pretty interesting. Some unique features make it stand out a bit from the typical FPS, but I'd have to play a bit more of it to say it is really great. It has potential. Having read about it in a magazine, I know the story already, but the demo only gives you a hint at where it is going.
Fun, arcade style racing. Using the same engine as DiRT, it looks great but doesn't quite have the best physics. Damage modeling is great, if a bit too severe, but overall a fun game.
