Really awesome. They’re all contained within my home directory too, so when I swap distros I can just copy my home dir and all my installed apps are carried over that way. Super useful feature that never gets mentioned! The downside to flatpaks is having to use them for cli in any way is a huge pain.
Happened to me where I felt loss if enjoyment over any game, that it felt like a waste of time and a chore. That eventually passed, definitely find them fun again.
