Just finished the game up. played on survivalist and my time was just over 7 hours.
thumbs way up. from top to bottom it's a much more polished experience. The flow of the game is much better and rarely was annoying with the situations the game put me in.
I would say that it feels a little less polished going into the finale though. Both games get start to unravel at the end and Dead Space simply goes crazy with the amount of shit it throws at you at the end but the end boss battle is really great. Maybe I'm just not a big fan of gauntlets in general but:

Having the gameplay devolve into just running down a corridor to the end while tons of enemies spawn all around me is boring. Plus I wasn't really a fan of the devs recycling the regenerator concept especially because it's not really very threatening by the time they introduce it. You've already upgraded your shit so much that it goes down in a few seconds. In the first game they introduce one early on and it's truly frightening getting chased by it. Here it was just a minor nuisance. and as I mentioned earlier the last boss battle in DS is great while this one is a little lame. It wasn't really difficult when I realized that 4 javelin shots followed by an electric burst kills her real quick. I liked it from a thematic point of view - just not gameplay wise.
worst of all - i accidentally hit cancel when saving the game at the end so i had to redo it all from the last save in the game going into the boss. beyond frustrating.
i'm better at talking about negatives so don't get the wrong impression. i really loved the game all the way through. its a really great way to start 2011.
finally i just wanna add the while i do think the game is really tense thanks to the awesome sound design - i don't think the game is as inherently scary as the first game. Dead Space takes place on a desolate space ship and to me just the thought of being trapped in a space ship with danger everywhere is really fuckin scary whereas Dead Space 2 takes place on a giant space station and i dunno... doesnt frighten me as much.
going forward i hope they try to shake things up for Dead Space 3. It's gonna be a little weird having Isaac go to a 3rd place and OH SURPRISE! necromorphs are here too.
