Clue.

I was making a joke about Col. Mustard on Facebook when it occurred to me that we don't have the game Clue here at our house. I used to play that game ad naseum and it's solely responsible for my career in law enforcement. It's a very basic "if-then" game of applying logic. I used to be pretty good at it. Especially when I peeked at the cards before putting them in the little envelope.
I would always wonder what crime took place in the mansion. Was it rape? Murder? Pirating DVDs? Either way it was up to me to pin it on one of the characters.
Mrs. White, Miss Scarlett, Mrs. Peacock, Mr. Green, Prof. Plum, and Col. Mustard were all guilty of something.
I would like to get this game to play with my kids but I'm afraid that updates to modernize the game may have ruined it. For example, instead of solving a crime you have to try and determine who is Miss Scarlett's "baby daddy". Or, perhaps charging one of the characters with a crime kicks off a very long, secondary game called "Due Process".
Regardless, it's way more funner than "Scrabble".
