Oddly enough our current 4E game is one of the least violent games I've been in- most of our opponents have been spiders and bunnies. Mind controlling bunnies.

And it's not like those CRPGs promote violence, the people seriously don't mind if you walk in and root through their stuff. That's why Morrowind was such a surprise, when accidentally clicking on the wrong item can get an entire city or wizard's guild screaming at you.
