If their vision was for this game to be an MMO/social game "from day one", then they should have done a way better job sharing that vision and framing the discussion that way.

The social/multiplayer aspects of Diablo, WoW, and SC are obvious to me, which is why Blizzard's move never really concerned me that much. Add on top of that the truly well done matchmaking system and I hardly think about it all. Doing things well goes a long way in convincing naysayers.

However, when I think SimCity, all I can think of is single player. And the vague things I've heard about interacting with others seem really lame. Again, maybe there are some awesome multiplayer aspects, but I have not heard of them and it sounds like most people aren't that interested in them.
