They could stop charging gamers a subscription to play the paid games (they “own”) online.
This is one of the key reasons why I own PS5, but I don’t play or invest in it. Even though couch gaming is much more comfortable for me.
I’m in the same boat.
Elden Ring, Helldivers 2, many games I’d get on Sony PS Store that I just get on Steam because I want to “own” the full game not just the offline part of it.
