I just played my first quest online. There was one other guy with me who died to some bees and left right away, so I figured I'd solo it. 45 minutes later I had gained 4 levels, and as I went to turn in the quest, oops, boss. Two trolls (lol) owned me. Can't be soloin' that!
Super fun, and the multiplayer structure is reminiscent of Monster Hunter. I just hope I am not forced to be Leonard too often in the main story.
