Sony forced the studio behind Helldivers 2 to make a PSN account obligatory after the game launched. That’s a pretty crappy move because PSN is not available in roughly 120 177 countries, so if you live in one of those you can suddenly not play your game anymore. And Sony hasn’t got the best reputation when it comes to securing and selling their user’s data, so players are pretty upset and vocal about this.
But I would say that present day Sony’s dick moves do not really fit in a topic about PS2 nostalgia.
