yes im glad star citizen tries hard to not fit the standard mold of most MMO games, but u will notice it is still a massively multiplayer online game.
a) it has single player. b) it has private multiplayer. c) it has instanced systems in the persistent universe, so you can't fleet battle like in EVE making it far less than "massive" for its spaceflight sub genre.
All three of these things work against calling Star Citizen an MMO. It's a multiplayer game, and you interact with people, and the universe doesn't reset when you log out.
It has MMO elements to it, sure, but so do games like Dark Souls and Diablo III, neither of which is an MMO.
Not every game with multplayer is an MMO. MMOs are online-only games where truly massive numbers of players (not 64 or 128 or whatever, but multiple hundreds and on into into thousands) can interact with each other in a persistent environment.
It doesn't have to be an RPG to be an MMO, but PlanetSide had hundreds of players shooting. EvE has fleet battles of hundreds to thousands.
Star Citizen should be a good game. (I pledged during the original Kickstarter. I follow dev mails. I have my alpha hanger software installed.) But the fact that it will be a good game and that part of it is persistent with limited players doesn't make it an MMO.
