On non of the official EA-sites I could find something about the Origin Access for FIFA 17 being something else than the full game. In fact, in the FAQ for Origin Access it says that it's not a demo, but the full game, so progress can be caried over. Then I found this, saying that not all modes are playable:
And right now I'm downloading the early access, and it says (demo) and is only 26.92 GB. So EA, why would you do this? I only got the Origin Access in order to play FIFA 17 early, and now I can only play two modes I really don't care about? As a customer, I feel cheated.
