If I wanted a great action game I'll play Gears of War, God of War, Uncharted, ect ect. Resident Evil were not action games, and I wish they would go back to their roots. I know it's been said it here like a broken record, but Capcom is just not thinking right in my opinion.
I'm always against Co-Op for horror games, to me it just takes out that being alone feeling, which it should be. Go back to good single player survival horror types of games.
I agree with Pat that they should reboot, and start with their roots. Go ahead and update controls and so forth, but keep the gameplay what it was during RE1-RE3 (or Code Veronica) that's what I want to go back to.
