Correct me if I’m wrong, but isn’t that page exclusively for games with native Linux builds? When people talk highly of Linux gaming these days it’s because of the work that’s gone into Proton, a compatibility layer for Windows games on Linux. You can play a large portion of Windows native games on Linux with minimal fuss now.
Also, publicity is a big factor. You pretty much guarantee some degree of media coverage when you do something like shut down a busy highway. I don’t think people consider often enough how important even negative press is in spreading the message.
