I've played a lot of FIFA 15 on PC and still sometimes do so, and I have a pretty high level. That level was taken over from FIFA 14, and so was the currency called FCC. That made it possible to buy a lot of the offline stuff, like new balls, kits and celebrations early on in the new game.
Is this also possible from FIFA 15 to FIFA 17? I've skipped FIFA 16 and am considering to go directly to FIFA 17. Both games (as well as the 14) would be linked to the same Origin account.
