This is why I wish Xbone had more cross-buy options like PSN.
To be fair, PSN doesn't allow cross buy on pretty much any retail title(as Origins is). If backwards compatibility pans out you will get that but the 360 GWG seldom gives out any Arcade/DLC/Indy games(I wish they gave out more Arcade games on 360) and X1 has mostly given out games that are X1 only(except Max and Guacamelee). Devs are moving away from PS360 development and most cross buy games on PS4 are PS4/Vita. Maybe games for Windows 10 will really take off and we will get W10 games to counteract the Vita games.
