I know, I've seen these people before. God bless 'em for trying to help parents sort through all the stuff there is out there these days, but they *seriously* need to lighten up.

There's a difference between playing a game like, say, Devil May Cry, and actually believing in occult stuff like that. It's just entertainment, after all, and playing it isn't going to affect your beliefs. Unless you're really messed up, and in that case you shouldn't be playing any games at all.
