Open world adventure games

[DragonRider]

Hello all!

I get tired of playing the same games...
I need to try something new. And because Google and Youtube are not very helpfull in finding games for my taste (allways showing NEW and "popular" games) I turn to my favorite forum.

And what kind of game am I looking for?
Short answer: open world adventure.... thingy...
Long answer: What I like a game to have is freedom. Freedom to explore, do many things and be what you want to be. A non-linear game. I want to be able to do what I want when I want. Freelancer Discovery is a good example in this case. I don't want to be limited in a game style of "kill this now go there and kill that then come back here to complete quest. Now repeat." Now when I think about it, it won't be easy to find a game like this. Also an important feature is to have multiplayer. Good multiplayer.
Oh and don't seggest shooters.

So.... any ideas?
