A Wiki that serves as a comprehensive manual for the online ice hockey strategy game Good Hockey.  It was started by players due to widespread belief that the game's built-in help system was less helpful than it should have been. It quickly became popular for players to create articles detailing their teams and best players as well.
"GoodWiki is a player-made manual. GoodWiki contains player bio's, team bio's, GHL Tools, and Game Help.
Anyone can create their own team page with team history, information, player biographies. GoodWiki is a GHL Source for the community, by the community." -Ryan0rz, GoodWiki creator
