Wikipedia is terrible for, say, political controversies, but it's just plain awesome for fanboy stuff like old computer games.

The Prisoner was perhaps the best computer adventure game ever, making up for its primitive 1980 graphics and limited universe by subverting the very nature of computer game-playing, even tricking the player with fake error messages into revealing a secret code that would cause the player to lose the game. It's disappointing that no one has ported it to modern PCs. Even the programmer's web page fails to give any useful links to where the game itself can be purchased, instead linking to various pages about the tv series (from which the Wikipedia page says it never received a license).
