The Hitchhiker's guide to the galaxy
Trivia, facts, etc.
HHGTTG gained a reputation for deviousness. "The Babel Fish Dispenser" was a particularly tricky puzzle appearing very early in the game. Failure to "solve" the Babel fish puzzle did not kill the player, but rendered the remainder of the game unwinnable. That particular puzzle became so notoriously difficult that Infocom wound up selling T-shirts bearing the legend, "I got the Babel Fish!"
The Infocom version of Hitchhiker's Guide quickly became a fan classic; it was one of five top-selling Infocom games to be produced in Solid Gold versions, with a built-in hint system not included in the originals. The game was re-released by Activision in several collection packages before rights reverted to Adams, enabling The Digital Village to re-release it as a web-based Java applet. Originally published as a fund-raising tool on the 1997 Comic Relief website, it took up permanent residence on Adams' own website the following year.
