Okay, people, it's out. I'm assuming no one's posting about it because they're all playing it.. hehe.
Two things I've noticed:
1) Even on my old standard-definition TV, this game is drop-dead gorgeous. Best graphics I've ever seen, bar none. Even after watching all those videos, it's still hard to believe until you actually play it.
2) I suck at fast-paced shooters.. lol. I'm dying left and right. Did manage to get one chainsaw kill in, that was fun. Not easy to get close to 'em, though.
I'm not going to say this is a Halo-killer, since it's not a FPS, and really is a totally different kind of gameplay, with the whole stop-and-pop thing. But it's definitely a killer app, and I think a strong contender for GOTY. It's a given that it will take the 360 GOTY, at any rate. It's still got Zelda to go up against.
