So (against my better judgement?) I picked up Resident Evil 6. I think this is the best way to put it.
Res 4 was a horror game with action elements.
Res 5 was a mix of action and horror.
Res 6 is an action game with horror elements.
Tons of ammo, press R to do wrestling moves on zombies, millions of herbs. Yeah, it's pure action now.
