So I’m finally getting an Xbox one this coming week. I originally purchased the original Destiny game on Digital(Xbox 360) back in 01/15 through Xbox Marketplace which included the Xbox one version. I didn’t see an expiration on this but I can’t find a way to confirm if the game will be available to me when I sign in. Anyone have any info on this?
It won't be available. Your account will also only transfer from September 2016. Destiny on Xbox One is different than on 360. At this point I'd recommend you wait until September and play D2 for free.
