Kingdom's Item Shop. It's incredibly fun. You basically are in a traditional fantasy RPG, only instead of being the adventurer, you're the shop owner they buy their gear at. You hire adventurers to fight in dungeons for you and you collect the loot. You sell the loot at your store, or craft it into more expensive goods to sell. It's incredibly fun and it's a digital only game so I strongly recommend grabbing it before the eShop closes down.
