Well yeah. Games that are inherently multi-player and not split screen and feature an aspect of matchmaking are obviously fine to be always online games as a service.
Although personally the games-as-a-service model is something I avoid even in those. Overwatch was made objectively worse when it went from the buy-once model to the pay-once-a-season-or-you-dont-get-the-new-hero model. Mauga is completely busted right now and every new introduction of a hero since 2 launched has felt exactly like this-- busted while paid-only players have access and then fixed after the free players get a chance.
It’s the model. Squeezing money out of players is slowly killing even multi-player games like Overwatch.
It’s completely and utterly unacceptable for single player games.
