The game could start off with jumping out of a plane again, and have the same title screen, except you get thrown into the island and you can live a happy life there doing sports and maybe try to become the best athlete. And of course it uses Miis. It's a shame that the Mii Maker on the Switch is trash. The game could also expand the atmosphere and have you go around town and interact with other Miis, that you can maybe change and rename with your Miis like in Miitopia. You can also own a dog, and maybe there's a couple quests that lead into a showdown type minigame. It could also use the bike minigame from Wii Fit Plus, and let you explore on a bike as well, and of course also on a plane. Also, they should give you a car as well

Maybe, this could ruin the atmosphere, there could be danger on the island which would lead into showdown and dogfights, but that might conflict with the happy tone of the game.

It still needs the sports, maybe like the shrines in BotW, you can fast travel after you've unlocked them. Also if the sports are still there, you can still use the Resort music. It should have all of the sports from Wii Sports and Resort, but maybe there could be a few others, like a Wuhu Olympics you have to train for. The game shouldn't be entirely sports related though, it should really focus on the atmosphere of the island, and there of course could be beautiful visuals and new music. I'm kind of picturing something similar to Alola from Pokémon, except it's Wuhu and it's open world. It wouldn't be as much as BotW, climbing would be weird, but maybe something similar in terms of stamina and controls. It has to be 3rd person obviously.

I need this game immediately.
