What world are people living in where "gamers don't want GaaS"?
I keep seeing this repeated over and over and then I go to Steam see games killing it and making tons of money long, long after they're already paid for. Goodness, Sea of Thieves sure crashed hard on Playstation, huh? And that bomb, Helldivers 2. And Palword, and Ark, and The First Descendant doing well despite "the crowded marketplace". Deep Rock Galactic has sold over 8 million copies plus being on Game Pass.
Many, MANY gamers CLEARLY play GaaS titles.
Sony should have cut their losses with this game YEARS ago, even if it had been a single player title. The lesson here isn't to stop investing in GaaS, it's to stop investing in bad games.
