I remember there was "monty pythons complete waste of time" on cd. I had a demo of it and I remember at some dinner with my family and my friends family almost everyone spent all the time after dinner in the computer room looking at this thing... ah, good times!
This game (the ORIGINAL Flying Circus game before all the others came out, including the waste of time one) had the best manual of all time. The booklet was made to look like the Hungarian Phrasebook from the TV show (my hovercraft is full of eels) and the actual instructions were only a few pages. The rest of the manual was this massive thing designed around all sorts of in-jokes, like guides to cheeses and a phony TV schedule and everything. It was great. And the copy protection involved you using the manual to identify certain types of cheeses using the pictures inside the book.
