The PS4 version of Hatsune Miku: Project Diva X has dropped to $39.96. Also on sale is Hatsune Miku: Project Diva F 2nd, which is currently $22.95 on the PS3.
VGChartz's Adam Cartwright: "Despite its somewhat anaemic lineup of backwards-compatible titles (unusual in light of the genre’s strong pedigree on Sony consoles), Vita’s selection of rhythm games is highly impressive in the modern market with genre favourites like DJMax, Hatsune Miku and Taiko no Tatsujin all present and plenty of quirky oddities like Deemo, Love Live & Persona thrown in for good measure. You’re definitely going to need to try your hand at importing to get the most of the genre here, but that shouldn’t be an issue thanks to region-free hardware and easy-to-grasp gameplay."
Hatsune Miku has become an international icon. What began as a singing synthesizer turned into a character recognized around the world that stars in multiple forms of media. In the realm of games, people recognize her as a rhythm game star. But what else do people need to know about her?
Play-Asia has reduced the prices on 8 gaming products including Collar X Malice for PS Vita and Disgaea 5: Alliance of Vengeance for PS4.
I only ever use Play-Asia for English-Asia imports anymore, it's too expensive to buy from them regularly.
