I picked up dead space on steam for $15 this weekend. A waste of money. I turned off the v synch and played with the mouse settings - game was playable, but painful. Some people have said you need to play the game with a game pad. The game felt like I was playing via console. Slow with cumbersome control. Assassins Creed was a little better, but still had a slow repetitive feel to it. Another FAIL for console game ported to PC.
