Maybe look into Bazzite if you get impatient waiting for SteamOS to become more widely available.

'Murica! Fuck yeah!

Maybe don’t flush alligators either.

Ooh, Limo has a Flatpak? Nice. I’m running Bazzite on my laptop and have been wanting to play FNV for the first time but I’ve got it on Epic through Heroic Launcher. I’m guessing the file paths will be different but it should otherwise mod more or less the same as you said, I’ll have to try it. What kind of weird stuff did you have to do to get NVSE working?
