Not any more than SimCity 2013 was an MMO. There may have been free-to-play MMO-like monitization of every little thing but the game mechanics are all single-player/small-group-of-players.
No, Asheron's Call was an MMO in every sense of the term. There was no free to play (at least in the pyreal scarab bug time period), monthly sub fee was it, and the game would have been wholly uninteresting without the full on massively multiplayer element.
Sorry, I was unclear. I was talking about Diablo III in my original comment and about it not having an offline mode or a mode where online play could be had on non-Blizard official servers (either dedicated server model or peer-to-peer).
