I agree that it looks a lot like System Shock 2 in a lot of ways, but it doesn't really give the same feel of integrated gameplay that SS2 had. Like, they talk about "hacking the security drones", but as best I could tell all that involved was clicking on them, and then for some reason shooting the pistol sets their target?
Also, the targetting seemed really lacking. I don't know if they'll increase that in the release, but I don't think I saw any crosshairs for the pistol, and I wasn't quite sure how the telekinesis thing worked, like if it just took anything in front of you, or if you had to aim specifically which could be annoying if there isn't much feedback.
Plus it looks really scary, and I'm a wimp about that sort of thing.
I love SS2 and Thief and AvP [though I can't play as Marine or I get too scared :p], but almost any other scary game/movie I don't really go for.
Also, I can kill you with my brain.
