Fantasy fantasy. I have an idea of using a fantasy dungeon instead of a farm. You'll still gather/farm/fish and craft, but instead of making your farm and town bigger (imagine stardew valley), you'll make your own fantasy dungeon. Imagine having slimes instead of chickens, or a golem instead of a horse, or instead of villagers you have skeletons/orcs/other creatures, and by crafting and selling the produce you make, you can make your dungeon bigger. All in a fun and comedy way. (Hope that by changing the setting am still within the rules)
