Not mentioned in the talk, among the onslaught of media and merchandise following the success of the game was "Q*bert's Quazy Questions". It was one of my most treasured books as a kid because of the cute illustrations and heavy cardboard pages. The jokes are only superficially related to the game, of course.

It is kind of hilarious to have a little story suitable for kids that stars a character whose one defining characteristic is "constantly swears".

"!%##", said Q*Bert. "What a lovely day".
