My Ds3 (14yo) loves his switch and so do his friends. He recommends Mario odyssey, and the Mario 35th anniversary collection has 3 games in one. You can get it on Amazon but no longer on Nintendo store. He said it’s really good.
He also loves and recommends for the switch: Zelda botw, Zelda Link’s Awakening Remake, and Animal Crossing New Horizons
