Meh. I really disliked Dead Space 2. The time altering ability made the game too easy so I didn’t put any points into it. Then I get to that one regen boss where you have to use it to open a flippin’ door before it smashes you. Really dumb to have an optional ability that becomes mandatory for like one part of the game (and to open a dang door at that). I never got past that door, and I never completed the game.
The first Dead Space is awesome though, but I’m not sad there won’t be a third fourth(???). Never would have bought it because the ability tomfoolery in the second.
