It seems like such a simple answer but honestly? Pokémon.
Outside of being able to pick a magical partner creature to spend my life with (or several if going down the trainer route) the world seems fairly idyllic and a genuinely nice place to live. Technology is reliable, people are mostly friendly, and on the odd occasion where major cataclysms occur, they seem to be very localised and easily solved by some random 10 year old anyway.
I don't think I would even become a trainer. I would just live ab ordinary, happy life with my partner Pokémon. Perhaps I would work at a Pokémon daycare or something.
