Making of Psychonauts
Double Fine was founded in the year 2000 and the first game the team set out to work on was to tell the tale of a psychic circus runaway and his quest to become an international psychic secret agent - in other words, a Psychonaut!
The Manual
Back when Psychonauts was released, games didn't rely on in-game tutorials to teach players about the game, instead it was common practice for games to ship with a manual. This was a printed pamphlet that explained how to play the game, so you could read it on the bus home, or to give you something to do while the game installed.
