I got a 2nd hand Switch last September and been playing on it most days. Put about 160 hours into so far, mostly made up of Zelda Link's Awakening, Super Mario Party, 3D All-Stars (Mario Galaxy) and 3D World + Bowser's Fury. I play these docked. On handheld, I enjoy the 51 Worldwide Games compilation in the car or when I'm at my parents (as I'm their +1 / support bubble thingy).
Theres plenty of cracking games on the Switch, I've just had it since launch so I have gone through a lot of them.
