If the headline above is causing you to send a side-eye in my general direction, hopefully the following will help explain things: basically, in the last few months, I've acquired a whole slew of Taiko no Tatsujin games.
Specifically, I've acquired five of them. I started with the initial Taiko no Tatsujin DS title, as some of you may remember, and it so pleased me that I quickly ran out (or ran to various places on the Internet) and bought the second and third Taiko no Tatsujin DS releases as well as the first to hit the 3DS. A month or so later, I added the third PSP iteration, called Taiko no Tatsujin Portable DX, to my ever-growing collection.
This particular entry in the long-running series is going to be called Taiko no Tatsujin V Version, of course--which I guess brings us back to my lame-ass header. (After all, in it I'm implying that this Vita cart should be re-named Taiko no Tatsujin VI Version, because it would be my sixth Taiko no Tatsujin game--har har. Don't worry, I'm not planning to give up my day job.)
As for when Taiko no Tatsujin V Version will hit the streets in Japan, how much it'll cost and all that jazz: the game's release date is July 9 and the price tag attached to it at that time will be 5,690 yen. Oh, and according to sources like gematsu.com and neogaf.com, it'll feature 80 songs and an RPG-esque mode called "Donda Quest."
If all of that sounds swell to you, and if you've got a Vita and some cash to blow, you can pre-order this sucker right now via amiami.com for just 5,200 yen (about $44).
