I really liked Underhand on mobile. It's a cultist card game from 2017 that's a uni project that is very well done. It has you manage cult resources while trying to appease a certain god. Every god has a certain way to be appeased and makes every run for that god its own different kind of gameplay with a deck of cards
Not available on newer versions of Android, damn! that sounded fun :(
As for my recco
If you can stomach the learning curve, Dwarf Fortress is an amazing game, if you haven't head of it, here's a quick review:
There's of course the paid version on Steam, which comes with graphics pre-installed and a lot of sound. The free version is updated alongside the steam version, so you won't be missing out aside from some QOL changes. If you go the free route (honestly, my prefered version, for a reason coming up) I would HIGHLY suggest getting the latest version of the Lazy Newb Pack, which comes with a whole host of QOL changes and the ability to apply a graphics pack.
This is a game you gotta have a wiki by your side at all times to play, but so long as you choose a place to embark that's away from monsters and in a warm climate (AND
DISABLE AQUIFERS IN THE LAZY NEWB PACK SETTINGS!!!) you'll have a reletively safe space to learn the basics and understand the controls.
Dwarf Fortress's fun comes from the stories it tells. Every little thing is simulated, look at the notifcations, read an interpriate them, check up on your Dwarves' thoughts, and watch as it all crumbles beneath you, so remember, Losing Is Fun!
