Well my question was should I get RAGE or DeadIsland, I chose DI.
Im guessing you know what DI is about, I know it's awesome because it's openworld and some rpg elements.
Since you said you wanted Fear3 greatly because of that survival mode; I dont think you should get it then, you dont buy a game just to play a single mode like in BO. Dead Island will be way more fun solo and co-op.
So I suggest DI ;]
