Duckman: The Graphic Adventures of a Private Dick is based on the popular USA Network animated series Duckman.
In this game, Duckman has been replaced by the new Duckman (who looks more like a super-hero than the old Duckman) and you have to take back your show. As the title might suggest, it is an adventure game, in the LucasArts-style.
The US title for this game was supposed to be Duckman: The Legend of The Fall, but it was never released because of a number of issues: 1) the declining popularity of the show, 2) the declining popularity of the Adventure Game genre, and 3) Playmates getting out of game software development.
Apparently things were different in Germany, where a localized version of the game was released (go figure.)
