Semi-related, what's with Sony PSN being so common in games? Ghost of Tsushima, new God of War both have it. Maybe fixable, but Ghost for example can't multiplayer on Steam Deck because of PSN. PSN not being available in anything but a handful of countries seems massively off-putting. I'd guess that cross-play has kind of become an expected feature these days, and just using PSN directly is the easiest integration path? Seems wild to me that suddenly this one very restrictive player is suddenly what everyone uses. I do wonder what other factors are leading to everyone not just integrating with PSN, but being PSN primary.
