Kinda surprised we're not getting a Million Live rhythm game or even a ML anime before this, tbh. They were kinda building up to it with ML idols being in the iM@S movie, that one interview where they said "An ML anime is being considered," and then the animated Dreaming! PV. I'm wondering if they'll announce something at the next live concert, perhaps?
Either way, this is great news for the franchise. Scamco also said the game has been downloaded over a million times so I think LIVE ON ST@GE is the perfect way to bring in more
money players, especially since Deresute is so popular.
