Greg Costikyan and others used the ParanoiaLexicon – a Paranoia wiki – to generate their new version, Paranoia XP.
Long long ago, the lads and I had a great deal of fun playing this, especially when run by my old friend, J, the BeetleGod, a genius at constructing ridiculously complex, rube goldberg-type, scenarios.
Wiki-based game construction: this sounds like something in which Lion would be very interested.
I hope you’ve seen the Game Design wiki & co. :)
