FINALLY getting around to playing this even though I've had it since release. I've just been focusing on Classic Mode so far, just trying out everyone that I can before starting WoL. I skipped Smash 4 so I've been focusing on those characters along with the newcomers for the most part. …unfortunately most of the ones I've played so far haven't left a great first impression so far aside from K. Rool (who's fucking ridiculous. I haven't been following the meta, but I'm sure he's getting nerfed) and Corrin, although I got a surprisingly high intensity/difficulty with Wii Fit Trainer despite feeling "meh" about her, and I'm interesting in trying Inkling some more.
Also the minigame before the boss fights is terrible. I'm not as big on Break The Targets as other people, but I wish we had that instead.
