Dungeon Maker is a fun little roguelike/strategy game I've been playing atm https://play.google.com/store/apps/details?id=com.GameCoaster.DungeonMaker&hl=en&gl=US You hire and level monsters whilst building a sorta dungeon with traps for heroes.
Since you mentioned Minecraft and farming simulator, both Terraria and Stardew Valley are on android, though I can't speak for their quality or playability.
Emulators are a pretty good shout, PPSSPP was pretty great when I last used it which was a few years ago now, so I imagine possibly better now and the PSP had a decent selection of games.
You could also try Google Play Pass for a month and look at a few paid games and see if anything tickles your fancy there, but subscription service.
