Nintendo will always be unique because of their exclusive software franchises and their style still seeps in.
The Super NES is basically just a "Nintendo Genesis" if you want to put it like that ... but would you ever confuse a Super NES for a Sega Genesis? Nope.
But maybe there is something to making a console that doesn't seem too toy like.
Even the Wii early on, was largely driven by adults who wanted one for dinner parties/Saturday night fun and the machine didn't like a Fisher Price toy like the GameCube did. It looked like a Apple-esque product.
Wii U's tablet looked way too much like "8-year-olds First Tablet".
The Wii initially also kinda toned down the mascot craziness a tad ... the Zelda launch game was dark/'cool' (compared to Wind Waker anyway) and Wii Sports had relatable sports like bowling and tennis and boxing without "Mario and friends" making it too wacky ... Nintendo Land on the other hand was really cartoony and didn't feel like a real place (why not just make it feel like an actual real theme park?).
