I'm betting they will gate it at a certain story point.That is true. I did not think about that angle with Origin Premier version. This will be interesting.
The other thing that we have not got any confirmation is with the EA Access/Origin Basic versions with the 10 hours is if it is a full 10 hours or until you get to a certain point in the game? I have played a few EA Access 10 hours trials where I got to a point in the game where it cut me off even though I was only 5 hours into the 10 hours. With some games, they lock it off when you hit a certain point. Not sure if this will apply to Anthem or not.
