Limited violence free roaming game?

My birthday is coming up, and I want to get a free roam game for either PC, xbox 360, or Wii. Thing is is that it can't have any violence in it, or if it did, I can avoid it. I like games like Sims 3 and Fable and Minecraft. If there's any game out there actually like this, please comment below.

Skyrim

Just try asking your parents for a violent game, hey it is your birthday. Violence doesn't cause harming in real life, scientifically proven.

The Witcher 2, there's totally no violence or nudity in it.
