PS3 exclusive due for release at the start of next year, it represents Studio Ghibli's first foray into videogames, and is being developed by Level-5, of Dark Cloud, Dragon Quest, and Professor Layton fame.
It looks gorgeous. I have no idea how it plays (other than it's a JRPG), and although the story appears to be overtly whimsical, it is Ghibli, so yeh.
A special edition is planned for the EU release (which does include both Eng and Jp voiceovers), which includes a full copy of the book from the game, which has a Bestiary and various tid bits of information regarding to the characters and the greater lore of the world. It's a hardback 300+ page proper leatherbound effort. Also it has a Drippy plush. Which is awesome right. It'll set you back £70.
Incoming~~~
Would definitely be worth a look for fans of the Studio Ghibli movies at the very least, in terms of artistic design this will probably be unparalleled this gen.
