MARIO & SONIC AT THE OLYMPIC GAMES

WII/DS, 2007

After years of rivalry, Sonic finally appeared in a game with Mario – and they decided to get all of their mates together in the spirit of friendly Olympic competition. It’s a pretty good party game featuring the usual array of track and field events, and it sold millions despite most Wii owners already having Wii Sports. The series has continued, with summer and winter versions to accompany every competition except 2018.
