First of all, welcome to the CFC and to the demogame. The demogame is one of the most interesting ways to play Civilization, and I hope you and several others lurking out there stick around and join in on the fun when we get things started next week.
In the demogame, we all participate in the playing of a single game of Civilization. All participants in the game are considered citizens of our nation, and we hold regular elections for various offices (the President, the Advisors, Governors, Mayors of cities, etc.).
Throughout the game, the leaders will post polls and lead the nation in discussions on topics relevant to the game. They will also post instructions to the President on how to play the game. Every few days (on a schedule established by the President), the President will play the game for a brief number of turns (normally between 5-10 turns at a time) and the cycle will begin anew.
What you are witnessing at present, is a rather lengthy discussion/debate on the rules by which we will play this game. I encourage you to take part in these discussions if you are so inclined. However, if you are not, I still encourage you to linger and take part in the playing of this game. You will likely find it to be a rewarding experience.
