So one thing I’ve seen on YouTube a bit is people saying that Forza Horizon 4 is only $10 – you buy it on the Game Pass and it’s yours. Except it seems that it’s more like $10/month rather than a straight $10. Maybe I’m wrong, but looking at the FAQ for the Game Pass, access to a game is lost once the pass expires or if the game is taken out of the Game Pass catalog.
So if there is a chance you’ll playing the game for more than five months, or if you plan on returning to the game from time to time in the upcoming years, you’re better off buying the game outright.
