your confusing EA Access with something else.
this is the full game for 10 hours, no matter what you are doing in the game, if it is loaded and sits on a main menu for 10 hours... you are done. so that is why everything says be sure to completely quit and do not just go to the home menu in XB1.
there was no EA Access NCAA trial.
if you have EA Access, you can download the 10 hour trial and play those 10 hours and be done with it. I do that for every EA title that gets added to EA Access.
the EA Access trial is NOT the Demo. the demo is completely removed and separate from the EA Access Trial which is the full game for 10 hours.
does this all make sense now?
