Even single-player games aren't single-player anymore with all the online-requiring bullshit publishers have shoved into their games. The game most likely comes with a fuckton of telemetry and user-behaviour tracking which is a lot more valuable to Sony if it can be attached to a specific user.

"Fuck you", that's their argument

At least with ghost of tsushima you only needed an account for the online co-op mode.

The same way Ubisoft, EA or whoewer else has their own fancy launcher.

Its an incredibly stupid thing but unfortunetly nothing new
