Same here. Sounds pretty sustainable to me!

Of course the most productive comment is the least upvoted one. EDIT: After thinking about it, maybe it’s best to add an explanation to bare links.

osu! is an amazing rhythm game. Try osu!lazer, it’s the new client: https://osu.ppy.sh/home/download

I also like Pioneers and Endless Sky, both space sims.

This might not count, but both Lichess, a chess website, and OGS, a Go website are open source.

There is also Mindustry, but I haven’t played it.

Maybe try Krita if you want a FOSS image editor. It’s good enough for my needs at least.

I’m using Evolution on Gnome right now, it does the job. Still hoping for Gnome Mail to finally have a GTK4 mail app…
