What 10 million sellers does the Switch have left?

Bored with Splatoon as an online game. I want a spinoff that has a larger hub world. Single-player game. Not as Splatoon 3. Just a spinoff. A much more robust single-player game. Maybe truly be the Nintendo JSRF. Ink Rival turf areas with graffiti. Or just maybe a 7-10 hour Single player Splatoon TPS
