Maybe half action/half horror. They did the right thing cutting the puzzles, making the bad guys faster, and changing the controls. They messed up by making it a 3rd person sci-fi shooter with no horror.
Make it scary. Make it fun. Since Dead Space 2 is going to be "Uncharted 2: Modern Warfare", maybe Res Evil 6 can be Dead Space? We'll see what the DLC content for RE5 looks like. Maybe it'll be what we're looking for..........
