Quiet as you like, Rittai Picross (Picross 3D) recently slinked its way onto Nintendo of Japan's release schedule, with a launch date of March 12th. As a puzzle game, Picross has never really relied on lashings of dialog, so this may just be import-friendly enough to consider buying!
That said, we do sort of fear this funky-looking update to the excellent first game. If any puzzle game on the DS has made us feel thick as mince, it was the later stages of Picross. Adding a third dimension risks driving us ever so slightly mad, as we attempt to wrap our mushy minds around the concept.
