You know, in RE4 you could see Leon's head chopped off, throat slit etc. Yet in RE5 they were all censored so you saw nothing. (Except maybe some of them, being impaled by that mantis monster or whatever it is.)
Finding new death scenes in RE4 actually became a little hobby of mine for a while. Shooting the lake is up there in my most shocking RE moments list. Every time I see someone playing RE4 for the first time I tell them to try shooting the fish before they get on the boat. Their reactions are priceless! Bahaha.
I thought being impaled by the Reapers in RE5 looked incredibly fake. The only death worth mentioning was when a Duvalia bites you in half, and it rarely happens (you usually just get munched and fall to the ground whole). Revelations didn't have any brutal scenes, either.
For some reason the violence is becoming more and more censored. Not sure why.
I can partly understand why they'd want to tone down the gore, but it just seems pointless. I mean, where could the game get banned? According to gamefaqs, RE4 was released in the US, EU, AU and Japan. I thought those were the most important market wise. And bear in mind that RE4 was way more gory than Resident Evil 5.
If it's, however, because of the forced multiplayer elements... then I'm afraid I've found yet another reason why forced Co-op is bad.
