Besides Switch 1, which past Nintendo system does Switch 2 feel the most like to you, and why?

None of them, honestly. It's a handheld. NES-Wii-U weren't. And the Gameboy-DS line were dedicated handhelds with their own games and own UIs etc. So the only thing the S2 can feel like is S1, only with a bigger screen and better specs. Sorry.
