It's not really an mmorpg, as the Towns and Outposts are the only stagnant domains.
All questing, partying is done in "personal" domains. If I'm not mistaken Everquest 2 or something is also trying this, but in addition to the original world for everybody.
"You can meet new friends in towns or outposts, form a party, and then go tackle a quest together. Your party always has its own unique copy of the quest map, so camping, kill-stealing, and long lines to complete quests are all things of the past."
So in other words it's diablo but instead of a chatroom with player icons you get to stroll around little towns and do the same thing. Don't get me wrong, though, I'm far from panning the idea. Whatever saves me money works for me, and having been a thousand plus-hour Diablo 2 player I'm dying to get my hands on this.
