When The Taken King expansion released, I purchased it in-game on Xbox 360 the moment it was available. I have been playing Destiny since day 1 of its release. I really do enjoy playing this game. I recently got an Xbox One and now I have a digital copy of Destiny through a friend's profile. The problem is, when I log into Destiny on the One, it says I do not own The Taken King. I have friends that only play Destiny on the One, and other friends that only play Destiny on the 360. I would really like to play with both sets of friends, but as I do not have The Taken King on the One, I am SEVERELY limited. I am not in a financial position to pay for another download of TTK. Is there any way to get TTK without paying for it, yet again? If not, I will continue my infrequent play sessions on 360 only and delete Destiny from my One altogether, as it is just taking up space.
You're going to have to pay for it again if you want to play on an upgraded system. Basically any game on old gen you would have to re-buy to play on current gen.
