I've read in the first post thah Black Flag's season pass (on sale today ^^ ) is cross buy: since i'm not at home i would buy the season pass on the website (so the 360 version), could i have any problems since i have only the xboxONE version of the game?
Least favorite Xbox One feature: limitations on used games and installation (installations, dlc, downloadable games and updates will fill that 500gb hard disk very quickly)
