Non-violent open world game?

I'm looking for a game with no violence, an open world, maybe multiplayer, preferably browser-based and with quests or missions? I like Minecraft but I've gotten bored of it. I like playing the GTA games but seeing as I'm not into violence, they get boring fairly quick. I recently watched a playthrough of Sleeping Dogs and loved it, mainly because the open world was so awesome and the plot was great.
Any suggestions would be greatly appreciated, thanks.

Added (1). Haha, I suppose I don't mind a bit of violence, I'm just not very good at fast-paced action or precision.

Added (2). I actually love the Sims 3, haha.

Sounds liek you'd love terraria, it's a 2d sandbox open world adventure game, and I love it. You should see some video's about it.

I think you would like Don't Starve on Steam. It's fairly cheap, and there's not much violence at all. Its much like minecraft (Crafting and surviving the night) your main purpose is to just stay alive as long as you can. The only thing you really fight is animals, and your own sanity. I'd recommend watching a playthrough first. I was instantly hooked on this game (I have 183 hours invested in it lol)
