It takes a lot to offend or shock me. Well, that's not entirely true. Heavy Rain and LA Noire shocked me when I nudity entered the mix, but that had more to do with the fact that I can still rememeber, clear as day, the controversy over games like Night Trap and the pornographic Atari titles.... Those games seem tame when compared to Heavy Rain and LA Noire. I love both games mind you; it just took me by surprise.
Some movies have offended me, like Kids, Gummo and Rob Zombie's Halloween. Still, those are rare instances.
