Does the online work now?

Yes, we're doomed basically. Nintendo doesn't care about Super Mario Maker 2 and there is no reason to expect great things for this game in the future. Probably, if there is anything substantial, we will have to pay even more (because $ 60 for the game + NSO is apparently not enough for Nintendo).

Smash Ultimate was released about 280 days ago, and the game's news section has about 90 entries. This means that approximately every 3 days, Smash players receive some feedback from Nintendo about what to expect from the game in the future.

In the case of Mario Maker 2, after 80 days after its release, we only had one entry in the news section... This game is definitely not getting attention from Nintendo. I hope that will change in the future.
