I didn't even bother to try Sidequest to be honest, just decided to cut my loses. And I don't have a secondary meta account, even 1 is too much given how much I trust that company. I also don't use facebook or whatsapp or any other BS, Reddit is as close as I get to "social media", if you can call it that. ;)
As for the "I ask myself if this doesn't work for some bug games.." part I don't know and honestly don't care anymore, I can't deal with a system where I don't even have control over my own save files, and where almost every single update seems to break rather then fix stuff and end up requiring a factory reset!!! :( Here's hoping Q4 will be better in this regard, way way better... #doubtful
