Sandbox RPG games with deep simulation and emergent gameplay elements cranked up to 11. Stuff like Dwarf Fortress, Kenshi and to some extent RimWorld.
I don’t know if there is a name for this genre and if anyone has similar games to recommend, please do!
Check out distrobox. It’s a way to have a Ubuntu (or any other Linux distro) container and allows you to install Ubuntu packages, even desktop applications.
It works great for when you need to install a random .deb file or follow a very Ubuntu specific step by step procedure. I use it exactly for this kind of stuff.
No rebooting needed, integrates fully with the host system, no virtual machine either.
