I've been thinking, and honestly I'd love it if there was a Harvest Moon (or RF) inspired game.
You could have your own farm, cultivate berries and other veggies/fruits, have farm Pokemon plus others roaming around to help, you could also tame some wilder ones, you could help build the town, get married, give your child their first Pokemon, etc. If it's more RF inspired than HM you could even go on quests inside dungeons accompanied by your partner Pokemon.
I think it'd be a super fun and relaxing game and I'm actually surprised such a thing doesn't exist.
