After watching Giant Bomb preview video about the game i realized that "1-2 Switch" game encapsulates the merge of Nintendo SPD (WarioWare, Rhythm Heaven, Tomodachi) and Nintendo EAD groups.
Also -- you've been lied to.
Main mode of 1-2 Switch is not minigames. The main mode is Team Battle which a board party game like Mario Party.
Structure of the each mini-game is like this: you pick a game, they you are shown a video that explains how to play and then you play it. Well that's pretty much copied from SPD's Rhythm Heaven.
But the bigger structure is that of a party game with two teams taking turns moving their pieces on a board, a-la Mario Party or Wii Party.
Actual mini-games are also reminiscent of SPD's signature manic crazyness. I want to present
"Gorilla" minigame which would fit right in a Rhythm Heaven game.
Runway minigame looks like taken straight from Wario Ware Smooth Moves with added competitive element.
Nintendo SPD was pretty much my favourite Nintendo studio and i love that their signature humour and style is very much present in new merged EPD team through games like 1-2 Switch.
