I finally received my copy of Project DIVA F 2nd last week. Hahaha! I can still remember the release of PDf back then was the reason why I bought a PS vita. New songs and button are introduced, and now you get to play levan Polkka(the tutorial song) in extreme mode once you clear any song in hard mode. And for those who had PDf, you can import your modules and items into the new game too.
