When we all found out that Super Mario Maker 2 wouldn't support online play, we kind of had a collective headshake. This is 2019, Nintendo is charging money for online services now, shouldn't this be a given when much smaller studios can figure it out?
It was such a big deal that the game's producer had to publicly address the issue during a playthrough at E3, and even went as far as to confirm that eventually, there would be an update that added that functionality into the game. That time is now, as Nintendo stealth-dropped version 1.1.0 of Super Mario Maker 2 last night. In addition to sprucing up the leaderboards section and adding touch-screen plus button building (at the same time) support for handheld mode (which is kind of a big deal, especially given that the portable-only Switch Lite is now in play), 1.1.0 also adds online into the mix.
It's of the co-op and versus variety for global play and folks on your friends list/players that are nearby. Between this and the addition of an "Official Makers" (read: first party) curated list, I'll be hopping back into Mario Maker 2 after a hiatus: these are by far the things that were holding me back the most.
