I have been running Bazzite on my TV for a few weeks. Was using PopOs however I was having issues with some games not launching, probably to do with the combination of Unraid VM, GPU passthrough, Xorg with fractional scaling on a 4k pannel. Bazzite with “Game mode” is amazing. Closest thing to Steam OS that I know about. Everything just worked with the exception of needing to firmware update my xbox controller to get it to work. Game mode seems to report as a steam deck.
“Steam Replay” it’s like Spotify Wrapped for Steam playtime/achievements.
And before Spotify was last.fm. Sadly, I think last.fm put all this behind a paid only account within the last few years.
