Yeah, I'm on gamepass as well, but ended up buying the season pass. My theory is at some point the base game will be super cheap, so if I give up gamepass I can always pick up the base game later. Although gamepass is such good value I doubt that I'll ever actually give it up.
good point. And with the ultimate pass update thingy I have gamepass until May next year so I have plenty of time to wait for a sale..
