Here is a direct quote from the link you just posted. "MMORPGs are distinguished from single-player or small multi-player online RPGs by the number of players able to interact together," "By the number of players able to interact together" in no way does Destiny allow a LARGE number of players to interact. Again, Destiny is NOT an MMO just because you play it online with a couple of your friends. How do you interact with other Guardians in Destiny? Via Fireteams, which I broke down in a previous post with the highest number you can have is 6. IMO, 6 people playing together in way can be determined to be a large number of players.
