bought it, finished it, loved it
i'm only truly disappointed by the lack of more boss microgames since nearly all of them are remakes from smooth moves but really, i can handwave a pass for that since it's got fucking mewtroid
also, probably due to my waning interest in vidya in general, but i strangely don't feel like i want to return to this one in the same way i wanted to keep playing Touched/D.I.Y./Smooth Moves. you clear the story mode pretty much lightning quick as expected, and while the story is damn good (wario being a villain in his own game is beautiful for the way it's handled), i'm not really caring about the post-game unlockables aside from music tracks and games.
another thing, the voice acting when you're replaying stages can get a bit... grating depending on the character. there's something slightly off about the way the voice lines play as well, past warioware games let the interjected voice lines pretty much flow with the other sounds/gameplay of the stage, but here it feels like the game yells them at you deliberately and noticeably louder than anything else. it's probably because they hired actual VAs for this instead of using compressed sound-bites from hell, but it can get a little annoying at times
doesn't stop me from loving the way the cutscenes were handled though, they're all really great
anyway despite those few nitpicks it's the greatest warioware game in existence by sheer amount of content, and i'm so happy it was made
p.s. it has the best amiibo content and nothing else will ever compare
