Nintendo recently tweeted the Mario Sports Superstars 3DS box art. As you can see the retail packing looks to have plenty of color. For a limited time Nintendo will be including (1) free amiibo card, which can also be purchased separately after the game goes on sale March 24th, 2017. The included amiibo card is advertised on the front of the box art. See links for purchasing Mario Sports Superstars for the Nintendo 3DS along with Mario Sports Superstars amiibo card links.
Mario Sports Superstars will bring 5 sports games into one, along with Mario & friends. Each sport included was designed to feel like a complete game individually. Hopefully this title will give 3DS owners something fun to play. Mario Sports Superstars will release on March 24th, 2017.
