Okami never allows you to rip someone's spine out or jam your hand (paw?) into their chest and tear out their still-beating heart. Okami and Mortal Kombat handle violence in two very different ways.

Also, the tobacco and alcohol references are more-or-less what you'd hear in an old fable as opposed to anyone yelling "Hey, let's go get skullskullskullskullfaced!" "Dude, I'm already totally wasted! *throws up*"
