Believe it or not, but I was actually there in Akiba for the release of this game. It was closing time while I was there at the game center but there was a still a line to try this game out. It was on the same floor as Maimai and Project Diva (and groove coaster, not by sega). Guess which Arcade games were the only ones with lines to play, Maimai, Project Diva and Groove Coaster.
Money talks man, expect more arcade rhythm titles from Sega.
Personally this game looks meh to me. Maimai is hella fun though.
