Did You Know?


Lead artist Peter Chan always puts the name of his children in games he is working on. The name 'Zach' as seen on the license plate of the broken car in the parking lot at the mansion is the name of his son who was born the same year. See more »


Hoagie finds dry spaghetti in the Colonial-era mansion kitchen. Italian cuisine did not make it to the United States until the 19th century. Therefore, it's highly unlikely someone would have pasta in their kitchen around this time. See more »

Just the best game ever!
29 November 2002 | by (Paris) – See all my reviews

In four words: The best game ever! Cartoon-like graphics, amazing music sound effects and voice talents! And the plot line is the best I ever seen, full of nonsenses and jokes... Too bad that Lucasarts has not released a game like that since.... hmmm Monkey island 3 or Grim Fandango! (With the ol' fabulous SCUMM system :) Now we must pray and implore George Lucas to obtain finally a sequel! (Maniac Mansion 3 :)... I hope that this day will come ;)
