Plain and simple: MMO: Massive Multiplayer Online Massive: meaning massive amounts of players can connect to the game simultaneously Multiplayer: meaning you can play competively or cooperatively with two or more players at a time Online: meaning you connect to the game and other players online MMO was an identifying tag stuck on games back before nearly every game with multiplayer allowed online game play. It served as an easily noticed element when browsing games to download. Since most MMO games back then were RPG games, MMO became commonly thought of as strictly RPG. Since then games have evolved and now nearly every game has some online multiplayer aspect. In this regard they're all MMO. Let's get this straight, MMO is NOT a genre, its an identifying tag. A genre is a category of something, FPS, RPG, SWS, Sports, Racing those are examples of genres. There is no game that is just MMO its set as MMORPG, MMOFPS and so on. For those that say, "but Destiny only has max fireteams of 6 and PvP of 12 it can't be considered MMO". destiny supports massive amount of players but like most console based online multiplayer games they've limited player counts in the same areas to keep the server lag down. "But that right there means its not a MMO!!" How? Because you can only see 16 people in the Tower? Yet every day hundreds of thousands log into Destiny and at least once a week that number hits the million+ mark, tell me how that doesn't qualify as MMO. "But Bungie said its not a MMO!!" they said its not in the traditional since, it borrows qualities of the MMORPG and MMOFPS then mixes them with the SWS to create a new, unique gaming experience. Throwing Destiny into a single genre doesn't work, its so much more than just one genre can describe.
