For what it’s worth GTA 5 is back on the service. It’s definitely not great when a game you’re in the middle of drops off gamepass. I think that’s in part why Microsoft is buying so many publishers; they want the games on the service in perpetuity. I will say that I don’t expect a move to fully streamed games any time in the near future, the internet infrastructure is just not there for it to be the only option any time soon.
