I just ran across the game Lexicon again, and it sounds like a heck of a lot of fun.

It's played on a wiki and the idea is that every turn you create an entry in the wiki (going through the alphabet one letter at a time) and cite other entries, which 1)cannot be ones you've written and 2) must be phantom entries when possible (that is you create the name of the entry but nothing else).

Here's the elevator pitch and the website where the idea was first published:

The basic idea is that each player takes on the role of a scholar, from before scholarly pursuits became professionalized (or possibly after they ceased to be). You are cranky, opinionated, prejudiced and eccentric. You are also collaborating with a number of your peers -- the other players -- on the construction of an encyclopedia describing some historical period (possibly of a fantastic world).

Anyone interested in playing? To keep it interesting, I'd be looking to recruit players outside of the Haven and encourage you to forward this along to anyone you think might be interested.

If we get enough interest, we can decide on the broad subject of the game.

I've gotten some interest, so I've set up a wiki to use.

If you are interested go here and tap in.

Hey, where is the game man??? I can't find it.

The game is all there in it's fizzled-out glory. A couple of players really stuck with it.

BTW, you realize this thread is almost 2 years old, right?
