I originally argued that it was an MMO. I figured since it was repetitive, had factions, PVE and PVP content, dungeons, raids, social areas, vendors, loot and gear-centric progression, it must be an MMO. But I changed my opinion over time, especially when I realized we were playing it like an MMO and that's why a lot of people disliked the game. It was through a further understanding of the game and Bungie's intent, that I realized the game was not at all an MMO. Instead, it's a casual FPS game with RPG and MMO elements intended for younger players. (Un)fortunately for Bungie, it was adopted by mostly hardcore 20-something players, who tore through their content in a matter or weeks. There are two possibilities at this point. Bungie may cater to the player base that is playing the game and make it more MMO-like in the future. They might also keep going with a simple RPG-ish online FPS game. That ball is in their court. I hope they find some middle ground. As it is, you can play Destiny pretty casually and still make decent progress in the game. Giving us time to play other games and have a life. But there are times when I sit in-game and wish there was something more, anything else to do after my dailies are done. If I was more into PVP, that would probably be a decent stop-gap, but I'm really not. So more often than not, I throw in another game or go play WoW for a bit. Heck, WoW has gone super-casual in this expansion. I barely played it between Destiny sessions and I managed to get one of my characters to level 100 with some ok blue gear. I'd still be 61 if this was Burning Crusade again. So no, my final verdict is that Destiny is not an MMO. But it could head in that direction in the future. If nothing else, look at those old weekly updates where DeeJ said he (and the devs) were learning new terms like "PVE." Clearly MMO was never on the table for them during development. Edit: Also "expansions" were another indication of MMO-like development, but they kept calling what was more like FPS DLC an expansion. Which really rubbed most MMO players the wrong way.
