Ok, I played this Xbox 360 thing for about an hour while loosers were standing in the cold rain outside waiting for midnight to show up so they could get thers (I work at best buy) (no, it's not what you think, i'm in the PC repair department). We had an HD tv set up and a booming sound system. The graphics were nice, but they didn't wow me at all. We had NFS:Most wanted and Project gothem racing set up.
Project gothem looked cool and all, but it could have used some more anti aliasing, there be jaggies all over the car. Most of the graphical improvements seemed to be off in the distance, like they put more work into tall buildings a couple streets over. The only things that really impressed me were the left and right side mirrors actually work (and break if you smash your car enough), you can look left and right in the vehicle (you don't need the Xbox 360's power to do this but it was a nifty throw away feature) and if you use the in-vehicle camera, the driver's hand actually moves to the shifter to shift the car.
Need for speed: Most wanted looked just like the PC counterpart, the only diffrence is that one of my co-workers had an iPod plugged in so we were listining to his sound track instead of the ingame music. Apparently, you can push that XBOX button in the middle of the controller and tell any game to use your MP3 player soundtrack instead of the in game sound track. I really wish revolution will force EVERY game to use custom sound tracks, I really want to play Metroid with the top gun theme "Danger Zone" playing in the background instead of the perfectly tuned ambient music that good games offer </sarcasm>
By the way, it took three employees like, 2 mintues to figure out how to turn on and connect the wireless controller to the Xbox 360 (I got to play first because I figured out how to turn the controller on) It's not quite as intuitive as the wavebird is to connect.
