I don't think it is worth getting at launch. I'm going to wait until this time next year to consider next gen.
I thought Dead Space 2 was loads better than 3. Dead Space 3 was so damn easy and forgiving that I barely remember the game. Also I don't think co-op should have replaced the multiplayer. They could have seriously improved the mp from 2.
I nearly always play in 3D. Currently playing Mario and Luigi Dream Team.
Every game that has been mentioned here I will be getting. Especially the TMNT games.
I might get Lost Planet 3 if it doesn't suck.
