Sony’s controversial PlayStation Network requirement for its PC games is once again in the spotlight after the company delisted the original Horizon Zero Dawn on Steam and the Epic Games Store and added the PSN requirement to the upcoming single-player remaster.
Sony hasn't done the paperwork to officially do business in those countries, so you can't make a psn account. And because Sony is intent on forcing psn accounts, it leads to this stupid situation where those countries are locked out, despite Steam supporting them.
