They blocked additional sales in 90 countries where it was sold initially. Folks that have it should still be able to play, with the exception of Vietnam since the country blocked steam.
Well I guess following privacy laws and setting up the infrastructure for the players to make a Sony account would be too expensive than the sale it would generate (plus the added data)
Right, but the game is already made. Sony was making money off the sales in those regions. They don't need PSN account data to make money off of the existing game. Just let people buy the game there.
