Going from the games shown at the conferences (in no particular order):
The Last Guardian
ModNation
Crackdown
Splinter Cell Conviction
Alan Wake
Galaxy 2.
Assassin's Creed 2 (I must be one of the only ones here who really liked the first one)
Modern Warfare 2 (If they fix the respawning AI!)
Cautiously optimistic about Forza, FFXIII, NSMBW and Metroid.
I don't have a PS3, so I've never played Uncharted, I'm not entirely sure what genre it is, even, but what I saw yesterday seemed to be some generic shooting and over-the-top action. Running through bullets?
Very nice looking game, however.
I didn't catch GT5, but aren't Polyphony known for being quite sly in releasing slightly-CG videos in announcements? WRC license is a big draw, mind you.
Halo ODST doesn't excite me at all. I had hoped they would move the gunplay over to something more like CoD/Far Cry 2/Las Vegas or anything like that, where actually aiming the gun and using the iron sights/aimpoint is vital for accuracy. This is the thing that's always kept me from really getting into the Halo games. I just plain don't like the shooting (also: humans>Elites>Brutes as for what I find fun shooting)! The Spartans are giant hulks of men, granted, and wouldn't need to do this, but surely a normal guy like an ODST would? That was what I was hoping for from this game, but it doesn't look like I'm going to get it.
Hopefully Halo: Reach will be more like this, what with it's squad-based mechanics.
