I just finished the game and cannot recommend it high enough.
User Rating: 9.5 | Dead Space X360
I am giving it a 9.5 because a 10 is for a game that totally rocks on every level. I would have to say that the only weakness I felt was that it was not long enough. I think that anyone who likes Space Horror movies to pick this up. The story was pretty neat and the game play and cut scenes were top notch. 3rd person shooter view really is the crème de le crème of this game as you see your character get pummeled left and right by these creatures that resemble The Flood from halo. But unlike the flood you have to strategically dissect them limb from limb to kill them and survive. Unlike Halo 3's lame campaign and utter lack of desperation- Dead Space has it all in spades. The last time I was down to just one weapon and 1 clip was in the first Halo- Combat Evolved. That was the experience of balance that made the game great. I felt that urgent need of desperation in Dead Space several times and made it out alive. It's these moments of balance with a great interface that make a great game. I really appreciate what EA has done on this new IP and look forward to the next installments.
Replay ability is also high due to the RPG elements incorporated in leveling up your armor and weapons.
Just play it already- you will love it.
