Osu! Tatakae! Ouendan

Osu! Tatakae! Ouendan, or simply Ouendan, is a rhythm video game developed by iNiS and released by Nintendo for the Nintendo DS handheld console in 2005, but only in Japan. Ouendan is about a cheerleading squad that rhythmically cheers on various people with problems in the manga comic book-style game. In each stage, players tap the DS touchscreen on specially marked dots that appear to the rhythm of various Japanese pop songs. They earn points for accurate timing and avoid poor performance, which can lead to the premature end of the phase. Although the game was never released in Western markets, it was a popular import there, leading to the development of its spiritual Western successor Elite Beat Agents and its direct Japanese successor Moero!
