I just spent some time reading impressions from one guy who actually went into good detail about many (non-spoiler) things, (and he seemed to actually be legit, to play the game thoroughly, as he has some screenshots and has repeated some things that I've been hearing about before from others. He's generally impressed with it, but it did not blew him away like the first game did. Even though he says it IS technically better in almost every way, he thinks he was maybe conditioned himself to expect too much, and he didn't think it was better by that much. There were 'wow, oooh, ahhh' moments in the game, though. The one thing he was supposedly not blown away by, is that the story was not very 'fresh' (I'm dumbing down what he said now, as I don't want to spoil anything for anyone, even though he never said any real spoilers in the first place) Also, one level in particular, was there that he never thought they'd put in the game. Another thing he said is that the graphics were mostly updated during the cutscenes (with heavy normal mapping and lighting effects), but during the gameplay it looked very simillar to first Halo. Basically, his feeling was that Bungie was playing it safe with this game. Like, 'more of the good thing' design, instead of surprising the players with something (overly) new.
