Yeah, I think it's pretty weird how they've been ignoring same console local play lately. For example, I was really expecting them to bring back an improved version of that local mode in Splatoon for the sequel when it was announced, but we got nothing instead.
This trend of having local play where the other person also needs to have a Switch plus the game kinda sucks, especially in my case since the Switch is not exactly common in Brazil and none of my friends have one. Where are the couch multiplayer games Nintendo?
