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.

Recommended.

Great game, lots of fun!
I had a great time with this one. It has a wide variety of songs, and lots of stuff to unlock. I guess the only real thing I'd like to see more of is a little more interactivity when designing Miku's room. It's fun a couple of times to watch her examine the objects you put in there, but when you realize it's just the same responses every time, it gets old fast. Still, for a music game, I suppose you can't be too picky, and the music part is very well-done.

Miku Hatsune : Project Diva
I love playing Project Diva. Project Diva came out in August of 2009 for the PSP and was #5 in the top 10 games bought in Japan within the August month. I bought and received my copy on Play-Asia.com and I haven't been able to put it down for the past Month and a half. This game has really intriguing gameplay taking in a from of a rhythm-style game. You just hit the corresponding buttons at the right time like DDR or Beatmania. The visuals on the game are simply gorgeous and all the Vocaloids are in this game. The replay of this game is also very high because once you have unlocked all the songs, there is so much more to unlock like costumes and furniture for Miku's home. There is also a collection of 200+ pictures to collect for wallpapers to use on your PSP. There is also an in depth create-your-own mode where you can chose a song off of your PSP and then create a dance and gameplay for that song. The possibility is endless!
