Personally, i had a mix of the game- me and my family visit the USA quite a lot, and the layton games came out while we were there. I think I have the american version of The Curious Village and The Last Specter, and the European versions of Pandoras Box and The Lost Future (I think)
Only thing I really noticed that I prefered Laytons voice actor in the European versions, though the voice in The Curious Village for Luke did bug me a little.
Im just gonna sit here hoping that its released for the normal DS.
The 3D effects really don't go well with my eyes.
