And now Diablo 3, Call of Duty, Quake, League of Legends, Team Fortress, Warcraft 2, Starcraft, Battlefield, Civilization and any multiplayer game or game with a mutliplayer component is called an MMO just because other people are playing it in their own little instances at the same time. You know, forget that we have descriptors for these games to seperate them into their own genres... forget what the word massive and multiplayer mean when combined... forget it...
I guess I am going to go just play my fav MMO. Its a board game that I play with only one other person. It's called Chess.
If you can't understand that MMO means a massive amount of multiplayers online in one game world/instance, and you instead believe that MMO means a massive amount of separate games in duplicate copies of the world... well.... I don't even know what to say.
