While most of the mini-games you’ll find in Mario & Sonic at the Olympic Games Tokyo 2020, coming this November, are (relatively) grounded in reality, three new “Dream Events” are being added to the rotation.
The new Dream Events include “Dream Shooting,” “Dream Karate,” and “Dream Racing.”
In Dream Shooting, you’ll run around a Japanese manor shooting targets and giant flying kites to score points. In Dream Racing, you’ll grab a hoverboard (much like Sonic Riders) and hurtle your way downhill while doing aerial tricks, grinding rails, and collecting Mario Kart-style powerups. In Dream Karate, you’ll try to take down opponents on a large platform that lights up in individual sections. Whenever an enemy falls by your hand, that section of the platform will light up with your team’s color, and whoever dominates the most space on the platform wins.
