Starfield and Forza Motorsport are coming to Game Pass on day 1. Both pretty solid reasons to stick around (or at least resub in a month or two) IMHO.
But the real trick is to keep an eye on Slickdeals. I got three years of Game Pass Ultimate for like $120 or something like that a little while back. Game Pass is so much better when it’s a fraction of the normal price! 🙃
