 He wrote his first game (a 16-room text adventure) when he was about 11 or 12 on the machine.Pitchford stated that he played "Colossal Cave Adventure" and was so enamored by the game that he used a hex editor to examine the code and partially figured out some of the programming concepts behind it.When a BASIC version of the game was released, he was able to review the source code directly, allowing him to determine how to construct his own text adventures, leading him into game development.
