Ark account and gamer tag
So I bought defiance for xbox but didn't know if my Internet connection would be good enough. And being that I don't have Xbox live, I didn't want to spend money on it if my Internet wasn't even fast enough. So I set up everything under my brothers XBL account(all 120+ ego codes, ark account). It ended up working just fine and I've put in a couple hours on it so I guess my question would be: can I now purchase XBL for my gamer tag and somehow transfer all my character info and ark account over?
