Remember how Sony sneakily added a PSN account requirement to Helldivers 2 after launch, thereby making it unplayable in the long list countries PSN still hasn't been rolled out to? And then Sony region-restricted a bunch of PC ports in those same countries, like God of War Ragnarok, Spider-Man 2, Ghost of Tsushima, and The Last of Us 2 Remastered? And then remember how people complained so much that was all undone?
Apparently Sony forgot the last step, because upcoming tag fighter Marvel Tōkon has been region-restricted on Steam in 132 countries that don't have access to PSN.
