2. Destiny
Just as Titanfall, Destiny will not include a proper offline single player mode (although it's playable solo). Created by the folks who brought us a decade of Halo, Destiny is a vast, Borderlands style, class based RPG infused shooter with a lot of backstory, some truly stunning artwork and all the other perks you can expect from a Bungie game.
Both Activision and Bungie said that Destiny will be a decade long project, so chances are Destiny is just the first of a number of games to be released later into the coming console cycle.
