Wait, what the hell, there's a dancing rhythm game spin-off as well? Eh, after the fighting game, I guess why not just go with it?
Like with Arena and Ultimax, the bizarre PS Vita entry Dancing All Night has way more story than you'd expect from something in the same category as Guitar Hero and Dance Dance Revolution.
This one takes a minor character from Persona 4 and spins off in a new direction, taking the series into the world of J-Pop. Its more fun than you'd expect, but honestly I have a hard time taking this one seriously.
