SMM2 is proving to be a really great follow up to SMM1. The jank is down to the levels being user-created. Not all creators are as talented as some ...anyone having fun with Mario Maker 2 so far, i think its pretty good though some levels can be jank though i hear this was an issue in MM1 as well.
But in general, the game is fantastic. Lots of new enemies and mechanics added, giving the whole thing a new lease of life. Already, the catalogue of uploaded levels is huge, so there's plenty to do in all gaming modes.
