I started it with a friend last weekend. I really like the antagonist pair, during the intro sequence all I could think was "You two are rad, can I join your crew?!"
We didn't get very far, maybe 2 hours maximum but had a good time with it. The crafting and item collection was a real departure, as was seeing health bars above enemies, but I liked what I played. Good price too!
Now about that Wiki-Bean-ia guy and his reach-around jokes though...
