The Idolm@ster games have always been incredibly fun, although most of us that don't speak japanese don't understand the menu or any bit of dialogue without having to resert to the internet. The only Idolm@ster games we got localized were the iOS versions of the Shiny Festa games, however alot of us don't know it exists, and quite a handful of us don't have an iOS device.
All that needs to be done to localize one of these games is to translate the menu and any bit of dialogue, the songs are fine; do what Sega did with Hatsune Miku Project Diva f. I am certain most of us will be content if One For All comes only as a Digital Title.
I started this petition because I would like to play an Idolm@ster game correctly, and I can guarantee you that there are many others just like me.
If this gets enough signatures, it may be able to convince Namco to listen a second time (the first time being Dark Souls PC port)
