I wanna buy Dead Space extraction very bad, but don't want to drop 50 dollars on this if i don't like it and my blockbuster doesn't carry this game yet so how does it differ than HOTD Overkill, and RE umbrilla chronicles? How much violence is there? i see IGN gve it a 8.5, gt gave it a 7.9, and wii.nintendolife.com gave it a 9 out of it. i wanna k now your opinions. I never played a or own dead space.
