Well, there it is, this strange game that could only have ever been produced in Japan. First released in the still striving arcades, and now parted to the 360, iDOLM@STER is part mini-games, part conversations with multiple choices. It's a really weird mix, but it's certainly working well enough to warrant this port in Japan.
This first video shows the first 15 minutes of the game, with some mini-games, some communication "lessons" and the important choosing of the girl's clothes. The second part will be online tomorrow, with the debut single and the first audition and TV coverage.
Update: Second part online, with a casting (good luck understanding what's going on!) and a rather terrible first TV!
