I'd like to see if there is enough interest in
Forum Nomic. For those of you who don't know, Nomic is a game in which a very basic "Constitution" regarding the game rules, and how to modify the rules themselves are given. The neat thing of a game like this is that you basically get to make the game whatever the players want. In person the game is difficult simply because of the logistics, but various "forum nomics" have been successful.
The original rules may have to be modified slightly to fit the format of a forum (for instance, the original Nomic has turn based play, this might be changed to 24-48 hour windows for proposing idea and then voting on them).
An example of a very successful forum nomic can be found
here.
I think an initial playerbase of anything over around 5 people would be enough to start- it would be easy enough to add in more later. This is basically just an interest-gauging post!
