@Edent We like those #games from @fdroidorg :
#minetest - like minecraft and hundreds of mods, also multiplayer
#unciv - choose civilizations, conquer & evolve technology
#shatterdpixeldungeon - walk through a dungeon, equip yourself, random levels each game, choose wizard, bow hunter and others
#hyperrougue walk through a 100 different worlds, collect orbs, defeat&befriend creatures - on a hyper plane, not the usual 2d or 3d experience.
