I remember, back in the day, when the ability for 32 players to play the same game all at one time was massively multiplayer. Quakeworld, for one. Guess I'm just an old salt now - that's "standard".
I'm still confused why all the hubbub over the nomenclature, though. The game will be what the game will be. If it will have 32 players playing on the same map at one time, then it will be a 32 player game. Call that MMO, call it just MO, or call it a rose - it will all smell the same in the end. Which is, to say, it will smell not entirely unlike a real rose. So calling it a rose is probably the worse of the three examples I gave, but I hope you get the Bard's gist: the point is what it smells like, not what you call it.
I wonder...if the only real conversation about a game is whether or not it should be titled an MMO or not, is that a good sign, or a bad sign?
