Maniac Mansion
In the early 1990s, LucasArts tasked Dave Grossman and Tim Schafer, both of whom had worked on the "Monkey Island" series, with designing a sequel to "Maniac Mansion". Gilbert and Winnick initially assisted with the project's writing. The team included voice acting and more detailed graphics, which Gilbert had originally envisioned for "Maniac Mansion". The first game's nonlinear design was discarded, and the team implemented a Chuck Jones-inspired visual style, alongside numerous puzzles based on time travel. Bernard and the Edison family were retained. The sequel "Day of the Tentacle" was released in 1993, and came with a fully playable copy of "Maniac Mansion" hidden as an easter egg within the game.
