As somebody who couldn't care less about competitive smash, this was the game I most had fun with in the franchise and would still rather play against most other games in the series. It doesn't take itself seriously and is genuinely a party fighting game that anyone could enjoy. Fun cast of characters second only to Ultimate and I remember fond memories playing this game at my friend's house where I'd play Meta Knight since he was my favorite Kirby character on the roster. How could I not mention Subspace either, one of the most fun singleplayer modes with an insane amount of references that anyone who is a Nintendo fan will absolutely adore.
