Yes, I understand what the popular definition of MMO is. Maybe a better example would be an IRC trivia bot in a channel with 1000 players, since that meets your rigid definition of massive. My entire point is that the genres aren't so rigid and that an uninformed reader could reasonably interpret any game where you can play with players all around world as "massively online multiplayer". In the annals of gaming history, MMOs are a very specific thing, but as far as the English language goes, massive doesn't necessary imply "X number of players on the server". Personally, I think like anything over 64 players and up counts as pretty massive but that's my totally arbitrary opinion.
