Woods is probably best known, however, for his role in the development of the Colossal Cave Adventure game, which he found by accident on a SAIL computer in 1976. After contacting the original author by the (nowadays nostalgic) means of sending an e-mail to crowther@sitename, where sitename was every host currently on the Internet. He heard back from William Crowther shortly afterward.
Given the go-ahead, Woods proceeded to add enhancements to the Adventure game, and then distributed it on the Internet. It became very popular, especially with users of the PDP-10. Woods can thus, in a sense, be considered one of the progenitors of the entire genre of computer adventure games.
He continues to work in the programming field, and to apply variations to various games.
