I like it.
I had the PC version of the first game on steam and it was enthralling, thoroughly loved every minute and had to play it again just because when you finish it you get the military suit, 10 nodes and cash. So I played it with the other three weapons I never touched and realised that entirely different things were possible, and some monsters couldn't be killed with some weapons. Never crashed, never hiccuped and runs smooth. Full graphics and once you get controls sorted, it is brilliant. Even the bits that are very similr to event horizon or doom 3.
I bought the deadspace extraction game for the wii because I wanted to see what went on to start with on the planet.
Playing through the second game now and it is just as slick, runs just as smoothly. Given it is a new release and so many releases are not tested and run badly nowadays, this game is refreshing in that it doesn't crash, hasn't got bugs and on full spec it is clear, crisp and sweet. And it is an EA game which makes a smooth running game even rarer.
Other comments on here seem to be on a downer but between this and something like mass effect 2 which was disappointing, or the halo genre. I would take this for quality and playability anyday. I hope mass effect 3 is like this and not the money spinning pile of crap the second installment was.
