This is the classic Parker Brothers whodunit board game (also known as Cluedo), reconstructed on a microfigure scale. The board design is based off of the 1986 version, which is probably the most recognizable version in North America.
The game is fully playable, with six microfigure suspects and six weapons. The only elements of the game not reproduced here are, obviously, the cards and each player's own 'notebook' to keep track of evidence, along with the 'confidential' envelope.
As there are many different licensed versions of the game (which is now produced by Hasbro)--Harry Potter, the Simpsons, Seinfeld, and Dungeons and Dragons to name a few--having LEGO produce a licensed version of the game would be logical, and it also fits in nicely with LEGO's own line of games, being made to microfigure scale.
The two biggest potential problems with producing this project would be:
(1) Getting licenses from Hasbro, which produces it's own construction toy, although their line is limited to Transformers models.
(2) The piece count might make it pricey. Some tricky spots such as the Hall and Conservatory floors, as well as the sheer number of small pieces required to capture all the fine detail put this LDD model at over 2,500 pieces. I have no doubt that a more experienced builder could cut that down substantially, and then if stickers were used in some areas (as much as I generally dislike stickers in LEGO sets), that could drop the piece count even more, probably down to the 1,200 range, most of which would be very small, as you can see in the photos below.
