I'll make a list: Kiosks so collectors like me can collect everything. (Exotics, shaders, emblems, ect) More vault space More bounty space/cashing bounties in from menu Faction and vanguard rep Faction rep without having to wear the faction class item A light system that's easier to handle (if a bit time consuming) for solo players More carry on items More objectives in patrol Emotes Actual cutscenes that don't leave more questions than answers More interactions and personality for NPC's And so on. I'm sure you get the picture. Year 2 is obviously superior.
