Okay, Halo is a platform exclusive. That means that PS will sadly never be able to get it. PS has platform exclusives as well. Destiny is a cross-platform game. That means that both platforms can play it. If the exclusives in Destiny were like Call of Duty, I'm sure people wouldn't mind (as it is only a month). However, in Destiny, the exclusives are for a YEAR. And when the next year arrives, the exclusives are obsolete as PS has new exclusives. See what I mean?
