Awesome Game
The game its grate, although kinda Hard to get used to how the game works, but after some time you get addicted, If you really like Vocaloids and Rithm games you need to buy this

Recommended for Vocaloid fans!
Personally I don't like rhythm games all that much, but this was really addicting!

At first, it was rather hard. But this is a game you can actually improve in the more you play. I think that it's important to follow the rhythm too.

The music is really great. There is a wide range of songs to choose from. Unfortunately, some songs do not have dance sequences.

The costumes are all really beautiful. The best part is that you can unlock the characters. That will take some time though.

However, if you are not a very big fan of vocaloid and their songs, you might not find it as enjoyable. Strongly recommended for fans.

This game is amazing!
I really love this game. Not only can you play as all the different vocaloid characters (Miku, Kaito, Megurine, Haku, etc!), but you can create your own PVs using your own music with this game. You can make your own levels! It's totally amazing and well worth the money. A great game, even if you aren't familliar with Vocaloid! The only problem is it really doesn't seem safe to be pressing your thumb so quickly... Play in small quantities! D:

Fun game, and very addicting.
This is one of the best games I have ever purchased. If you love Voc@loids, and rythem games, then I suggest you get this one!!

Something for all vocaloid fans
I'm not a big rhythm game afficionado so I won't rate this compared to DJ Max or Ouendan, suffice to say I have played the latter and think the production values on show in Project Diva are off the chart in comparison.

For anybody who has gotten into the Miku Hatsune scene there should be some fun to be found in this game. Featuring big Internet hits like "World Is Mine", "Ievan Polkka", and "Hato" the game will have you tapping your feet as you tap the buttons. Each song has a lovingly crafted musical video featuring either a 3d Miku performing or a montage of 2d images.

From a gameplay perspective I found the rhythm arrangements to be mostly on par but a couple of the songs seemed to be completely mis-timed which made them frustrating to play. Similarly the difficulty level you play songs at seems to have little to do with the complexity of the arrangement with some songs on normal being markedly easier than others on easy. The game will keep you going for a while though as with each successful performance you unlock outfits for Miku and items for her room where you can watch her relax.

And if you find your favorite Miku track missing from the game on its soundtrack the game lets you take your own tunes and create (and choreograph) your own rhythm challenges which should keep the more musical players going for a long time.
