It's from PC Gamer, so I think it's safe to say they mean worst gaming company in the world. They could have said that though.
Even limited to gaming, EA, Ubisoft, and Activision have always been pretty much tied for it. Now Activision is part of Microsoft, and I think with both Activision and Bethesda and the shit the latter has caused lately, I think we can bump Ubisoft out. And I think when Copilot gaming rolls out, whatever they're calling that, they'll be worse than EA was before. The problem with EA isn't so much what they were before though, it's what they'll be under SA leadership.
Gaming by megacorps has never been good for gamers, and it's going to get worse. And yet people keep supporting them.
