Limited in scope, but that actually gives it a decent amount of purpose. This is immediately obvious with its transportable nature - less impressive now with Smash Ultimate, but unique at the time. But there's other stuff too. Smash Run, while perhaps not as reliably fun as City Trial, is still a neat experiment and good for a couple runs. The lower technical capabilities meant the game would need to experiment with its stages, lending itself to personal favorites like Magicant, Unova Pokémon League, and Arena Ferox. Both "Smash 4" games sharing development assets means that Smash for Wii U is less ambitious as a result, but Smash for 3DS's ability to replicate the Wii U title's physics and gameplay is all the more impressive.

I think I'm generally okay with leaving Smash 4 in the past (revisiting it, I was shocked at how little there was to it), but if I tripped and had to play one of them, I'd rather this game than the Wii U one.
