Forza 1 week. Flight Sim was fun for less than a week. That’s ~2 weeks. One subscription for GamePass is 30 days. If you cancel before the 30 days, you get a refund for the remaining time.
It’s quite literally a no brainer to take advantage of GamePass right now.
People who will comment “ya but you don’t own them anymore”, I don’t care. I have 0 urge to play either game, because they are finished. I essentially saved $280 CAD playing on GamePass.
