Well played the retail version a bit last night.
It looks exactly the same as the demo, maybe slightly more polished (I jumped from one to the other a couple of times in the same area).
- Install is actually 3.73GB even though the box says 5GB. Install time about the same as GTA4, which is pretty quick
- There is NO 1080i support, like the demo. 720p only
- Game is very solid and polished, I didn't see any load times once the game started - looks like they are streamed in during the realtime cut-scenes
- Voice acting is goofy
- Game theme is surprisingly interesting.. especially when the whole crew is intent on getting high on the Nectar before a battle.
- Online functionality is very nice (like the demo), in-game friends lists, you are "always connected" and can easily jump into co-op/multiplayer or invite friends
So far, it certainly no COD/Halo/Gears/Resistance, but it's definitely better put together than most of the other forgettable, recently released shooters.
I predict review scores on average of 7 or 8 out of 10.
