Know there's a couple gamers on the site so figured I'd do a quick review:
Played it for about an hour or two this afternoon. Buy it. It's awesome. One of, if not the best few opening hours of a videogame I've ever enjoyed.
Combat is a ton of fun - Great balance between using your weapon and using a melee (or potion if you have it). Kind of similar to Left4Dead in that it's open a 50-50 or 60-40 split in what's necessary.
And as a guy with short patience I absolutely LOVED that it has a button which tells you what direction to go whenever you need it. Generally the path is fairly obvious, but idling around trying to find the right place to go is always super frustrating for me.
I'm not a huge storyline guy (one of the things that deterred me from continuing through 'Mass Effect 3' was all the cut scenes) but the game does a good job of telling a story without taking too far away from the gameplay. And so far, the stories REALLY interesting. It's a little "Bourne Identity" in that you're not exactly sure what's going on around you and why certain events are happening. And you can some really SUPER creepy vibes from the town and townspeople.
Sure the reviews got everyone excited, but I figured I'd relay the message from a super-casual gamer who generally leans to sports games.
