I'd like more games around cooking. Not really Cooking Mama like, more like...
RPGish?
I thought for some time a One Piece cooking game could do well. You play Sanji. You make sure the ship is stocked. Maybe it has a bit of roguelite, you don't get to choose what islands you go to, but are just told. Then you can ask various crew members to pick up ingredients while out. Maybe fishing minigame on the ship or at the islands? Maybe some random encounters where various npcs come and board your ship and you have to feed them and if they're happy with the meal, bonuses or stuff? Keep each crewmate happy and they perform better during excursions!
