I hope with this one that the Toad Scramble-style thing isn't the only kind of board gameplay, because I really don't think it's as interesting as either classic or car gameplay. I also hope that there isn't too much stuff if any that you need multiple Switches for, I really hope that's just the trailer showing off what the game can do. We barely use handheld and never tabletop mode, so I hope not everything is exclusively for on the go stuff, and that it's integrated even if slightly differently into the docked mode.
Also what do you think's going on with Shy Guy, Daisy, Waluigi and Bowser Jr. in the top right hand corner of the box art? If the four in the raft on the other side's anything to go by, I'd guess it's some kind of minigame (I'm thinking like
Boogie Beam), but I'm not sure, it definitely seems weird.
