An absolute favorite for most of my childhood. Clue (known as Cluedo in the UK) takes place in a huge mansion, with the game board divided into different rooms of the house. There are several characters who are house guests. The owner, Mr. Boddy has been murdered. The objective is to solve the murder, by determining Who, Where and How. (suspect, room, and weapon). It was fun to solve the mystery and scream out: "Miss Scarlet, did it in the Library with the Lead Pipe!!!" I was a mini sleuth!
If I've missed any great games of your childhood...weigh in with a comment and let me know.
