The original unreleased Maniac Mansion board game

Does the concept for this original game still exist? Or did it went the way of the lego pirate ship?
Would it have been close to a potentially releaseable state? Or would it be no fun to play after the original rules? Maybe if you tweaked it a bit, could a fan made version maybe be a non commercial project for the future?

This sounds interesting.


I’d love to see that released. Could even make a Cluedo (Clue) version!
