This game might be worth a rental if you really love Dead Space. I liked the game on my PS3, but the Wii version just can't compare.
As has been mentioned it is rail based so you don't control movement. The graphics are okay for a Wii, but hard to look at after you play on a PS3 or Xbox 360.
The story seems good. The controls are pretty good. I could have done with a little less swearing as frankly it just got totally unnecessary with the volume of cuss words. I know it is mature, but not every sentence needs someone cursing.
It could be worth a rental, but I see no point in buying the game.
Game play was ok. A rail shooter style game, but had way too much movie and commentary. Was actually a really short game, if you took all the other junk out. Kinda had a bit much gore but graphics were ok.
