The Idolmaster One For All (アイドルマスター ワンフォーオール, Aidorumasutā Wan Fō Ōru, officially stylized as THE iDOLM@STER ONE FOR ALL) is a Japanese raising simulation video game in The Idolmaster series developed by Bandai Namco Studios and published by Bandai Namco Games.
The story in One For All is told from the perspective of a producer in charge of leading and training a group of pop idols to stardom.
The office environment was redesigned to give it a more natural feeling, and a focus was put on "returning to the starting point" in The Idolmaster series with One For All centered on growing alongside novice idols in a small talent agency.
The Idolmaster One For All is a raising simulation game in which the player assumes the role of a producer who works at 765 Production (765 Pro), a talent agency that represents 13 pop idols who recently made their debuts but have yet to make an impact in the industry.
At the beginning of the game, the player meets Junjirō Takagi, 765 Pro's president, and is tasked with initially choosing to produce one of the agency's idols: Haruka Amami, Chihaya Kisaragi, Yukiho Hagiwara, Yayoi Takatsuki, Ritsuko Akizuki, Azusa Miura, Iori Minase, Makoto Kikuchi, Ami and Mami Futami, Miki Hoshii, Hibiki Ganaha, and Takane Shijō.
At the beginning of each week, the player organizes the idols' schedule, which includes activities such as lessons, consultations, promotional work, stage performances and shopping for costumes and accessories.
[4] The lessons are instructional sessions that idols partake to temporarily raise their image points for one in-game week, and are in the form of three minigames.
[4] This communication aspect is also featured during promotional work, which are jobs that the producer and the idols can take to further their popularity in specific regions.
The player and the idols are scored by the accuracy of these presses in timing, for which he or she is given one of four ratings: Perfect, Good, Normal, and Bad.
[2] The idols' performance are also represented by the voltage meter, which increases as the player successfully hits a note.
The player also has the option to use memory appeals to reset each image's interest rate and receive a boost in the score and voltage.
This includes such actions as raising vocal, dance and visual parameters, increasing the speed at which the voltage meter is filled, and strengthening the effect of memory appeals.
Sakagami explains that the true charm of The Idolmaster is to grow alongside novice idols centered on a small talent agency, and he goes on to say that the direction One For All took was in depicting the "warmth" that goes along with "765 Pro as the starting point".
[3] Sakagami goes on to say that he wanted to remove the one year time limitation because of his strong desire to allow players the chance to produce the idols until they would be satisfied.
The idea for this system is derived from the use of amulets in The Idolmaster 2 which adjust gameplay elements, and skill points work in a similar fashion.
[11][12] The Mainichi Shimbun reported that one day after the game's release, both the limited and regular editions were already sold out of stores in Akihabara.
