The best handheld/console rhythm game I've ever played. Usually the arcade experience is unbeatable with rhythm games, but IA/VT matches that easily. The tactile feedback from its control system using the vita buttons is extremely satisfying and far superior compared to other control schemes I've experienced (Project Diva, Persona Dancing, etc.). The music selection is excellent for even non-vocaloid fans too, with a wide range of coverage genre-wise and difficulty level-wise.
