Rhythm Heaven Megamix

Rhythm Heaven Megamix, also known as Rhythm Paradise Megamix in Europe and Australia, Rhythm Tengoku: The Best+ in Japan, and Rhythm World: The Best+ in South Korea, is a rhythm game released for the Nintendo 3DS in 2015 in Japan, Hong Kong and Taiwan and 2016 in the rest of the world, and the fourth installment of the  series. The game largely consists of games taken from past installments, along with handful of new ones.
