Because the reason why I'm asking is because I don't have a PC just Xbox and Playstation 4. So I'm trying to make my Xbox as my main platform to where I can move over to PlayStation 4 with my character. So I'm wondering if it's possible without creating two other accounts like battle net and the other stream account?
You can use the characters from your chosen platform on any other platform be is a Xbox, PlayStation or PC once you activate cross save. PS. This is a D2 subject and should have been posted on the #Destiny2 forum page not one set aside for D1.
