The press release describes the game:
Up to four players can solve crimes all over the world to unlock the secrets of Mr. Valentine's grand scheme as the Wii Remote is transformed into classic detective tools, such as a magnifying glass, flashlight, lock-pick, fingerprint kit, and more. Players then discuss and piece together the clues in their detective notebooks to deduce the identity of the culprit and crack the case. Once the mysteries are solved, players can play again with a new set of clues, suspects and mini-games with a different experience every time.
Early praise for the game has been centered around the character design, which could be considered to be on the level of a main Disney property.
I (kind of) hope this is more "family" oriented than "kid" oriented. I'd like to have fun, mystery case files type game to play with my wife on the tv.
