Yep. Even as someone who frequently subscribed to Game Pass, I mostly used it as a "Try before you buy" demo service more than anything else. I calculated the cost of subscribing every month vs. just buying a game outright and taking the time to finish it (however many weeks or months that would take) and just buying the game during a sale turned out to be cheaper.

It's great for discovery, but not a great deal if you pay every month just to play 1 or 2 games. Particularly if those games take a long time to finish, like Persona 5 Royal. The less time you have, the worse of a deal Game Pass is. That said, I still think it's good to sub for a month just to try a bunch of games if you're thinking of buying a new one.
