The iDOLM@STER: Million Live! - Theater Days

THE iDOLM@STER Million Live!: Theater Days is a spin-off of THE iDOLM@STER Million Live!, following in the footsteps of Cinderella Girls and Cinderella Girls: Starlight Stage. Rather than a social media game, it's a rhythm game. A total of 52 idols, including all of the original idols from 765 Productions, all idols introduced in Million Live!, and two new characters are playable, who are all represented in 3D during gameplay.

As usual, the player takes on the role of the Producer. After the success of the original 765 Pro idols, the president decides to start the 39 Project, fittingly consisting of 39 idols. A new secretary named Misaki Aoba is introduced, who helps the Producer.

Idols are split into three categories: Princess, Fairy and Angel. Gameplay consists of tapping icons to the rhythm of the background music. This includes simple taps, tapping two icons at once, tapping and flicking the direction indicated by an arrow, tapping and holding, and tapping and holding while sliding to keep up with a moving icon. Cards still play a role as a way to scout for new idols and to do in-game collecting. They can be obtained via Gacha, using in-game currency called million jewels or gacha medals. Costumes can also be obtained through Medal Gacha. Different modes, like MV Mode and Solo 2MIX+ Mode, can be unlocked by clearing songs at least once on any difficulty.
