When I say Halo-level, I meant the quality and size of the multiplayer. Halo 2 and 3 had incredible multiplayer modes. Destiny has a very amateur multiplayer. I don't think people will be playing singleplayer all the time because it's linear and relatively short and after that, you have some Strikes and Raids which will be boring after you get good at and used to all of them. After that point, there's not much else other than Crucible which is a low-grade Halo and people will stop playing because it's amateur and doesn't have that addictive effect boring FPS games, like CoD, has. CoD has a style, atmosphere, and many bursts of rewarding feelings that gets you hooked on it like some drug. Destiny's Crucible is not much multiplayer-wise and doesn't have that addictive effect some FPS have. EDIT: Just fixing some spelling errors.
