I'm genuinely interested in this (because it has a free option and because I have a Shield TV) but for the life of me I can't figure out where the hell it lists what stores are supported. I'm sure it supports Steam and I heard it supports BNet, which is great, but I also have a huge library on GOG and a smaller library on Origin, UPlay, and EGS. Are those supported? Their FAQ (which is buried [nvidia.com]) doesn't say.
