Rhythm/music games tidbits
DDR used to be called Dancing Stage in Europe, to avoid association with Europe.
What we know as Just Sing, a continuation of the Singstar series, got 2 games in Europe promoting the Now That's What I Call Music label, with the titles "Now That's What I Call Sing" and "Now That's What I Call Sing 2" respectively.
Fan Club, Fan Club 2, The Dazzles, Airboarder, and Cosmic Rhythm Rally were completely redesigned for Rhythm Heaven Megamix.
WarioWare and Rhythm Heaven often reference each other, due to being made by the same developers.
Two DDR characters are named after music labels, Emi Toshiba, who's named after Toshiba Emi, who made the Dancemania albums, and Yuni Verse, who's named after Universal, who purchased out Emi.
