I haven't noticed a difference.
I did notice that they got away with a whole dang lot for a T rating in this game, though. Blood, tons of violence, strong language, use of alcohol (OMG DRAKE IS DRINKING A BEER) and tobacco (OMG SULLY IS SMOKING A CIGAR), etc.
ESRB sure is laying off on the ratings recently. I guess you have to make a game like God of War 3 to get an M rating these days.
