Expansion Question

[Taliph]

...But you can still play the game you bought the expansion for on the system you bought the expansion. I really don't see why you need to play it on 2 different systems, what is the point? Like really, I don't understand the waste of money in having the same thing on another system when one is all you need.

I have both because my ps4 is infinitely more portable then my pc.
