This game is awesome and everyone should try it. Also everyone I know who played this thinks is awesome. Even people who don't game! I am not surprised by these sales. I hope this convinces Sega to bring more of their classics on the Switch. Maybe something like Monkey Ball or some Dreamcast titles?
Also the game is perfect for the Switch. You can play two players right out of the box and getting two more controllers is not as expensive as other consoles. If someone else has a Switch then all you need to do is bring their pair. This game is so fun on 4 players. On par with Mario Kart and Bomberman.
