Paranoia, the classic role-playing game in which players battle a mad, totalitarian computer for their freedom ("a light-hearted game of terror, death, bureaucracy, mad scientists, mutants, dangerous weapons, insane robots, and technological satire that encourages players to lie, cheat, and backstab each other at every turn") has just re-launched with a new version that was collaboratively developed with players via a Wiki, borrowing "the tools and methods of open-source software development for a paper game."
To a large degree, the game was developed online, in public. Fans of the game contributed enthusiastically via blog, wiki, and online forum. They wrote text, debated rules, proofread, ran statistical analyses, and even wrote a computer simulator to test the game's paper-and-pencil rules.
"Online collaboration made this edition of Paranoia the best yet," said Allen Varney (www.allenvarney.com), the game's designer. "We borrowed the tools and methods of open-source software development for a paper game, and it worked brilliantly. I plan to create future games the same way, and other designers should consider it too."
