I honestly think Resident Evil needs to return to the style of RE4.
The old Resident Evil games are simply too clunky. Resident Evil 4 was a great mix of survival horror and action.
To be honest, even Resident Evil 5 is pretty good. I don't really see the difference between RE4 and RE5 to be honest. They were both practically the same games, except the latter lacked the scare factor.
I like the combat in RE6 as well as all the moves you can pull off though. Take the best from RE6 and combine it with RE4 and I'll be happy
Also, am I the only one who likes co-op? I can't remember the last time I shelled out money for a PS3 game, but co-op is great. I enjoy games more when playing them with friends, than on my one. It also increases replayability.
