Hello,
Your idea PBEM Enchanged sounds similiar to my idea Civilization: The Real World, CIV:RW for short.
I've popped in/out of the civilization community for about 5 years, but I'm pretty outside of all the details. Last year I became a citizen of the Demo game and visited it a couple of times, posting maybe only 2-3 topics. I loved it, but I lost interest extremely fast and moved on thinking that it could be better run. At that moment I thought of the idea of creating an entirely self-based website to administer a massively multipler realistic game setup with civilizations controlled by individual groups that decided on THEIR own how they ran their civilization. In a nutshell: A Civlization Game UNLEASED to represent civilization and it's advancement in real life.
So, this is really BIG and includes some fundementals that were recently brought to the board in your topic, so I am glad I read it.
One is that there would be no government structure decided by the who sets up the game, because civilizations govern and structure themselves.
Another is it would be multiplayer/multi-team.
Lastly, since it is so big, is that it would be on it's own website. I will get to that later.
--------Some Specifics------------
The game is called Civilization: The Real World, Civ:RW for short. It would be played on Sid Meier's Civilization 4, Civ4 for short, and referred to as the "game file". It would be adminstered by a staff referred to as "game setup" staff. It would be particpated by anyone that registers as a "forum user". In real life, this can be considered "Life", "History", or "The Real World" which is controlled by "God", "Nature", "Weather", or "Natural Forces" and lived by "People", "Specialists", and "Leaders".
To put something like this on, there would be some rules. Consider these "Laws of Nature". In this game, they'll be called "Realism Rules". These are important concepts that make the game realistic and FUN. These rules are meant to help aid the game's realism ONLY.
Realism Rules
POPULATION:
"Population" is the amount of people in the game.
The game setup determines "population" by the amount of "forum users" playing a part in the RealCiv (Civilization: The Real World) game.
The game file determines "citizen amount" by the population in the Civ4 game.
For every one (1) "citizen unit" in the game, there must be at least 2 to at most 10 forum users on the website accounted for that citizen unit. This can be considered a "family", "household" or "working class" unit.
If the population is lower than citizen amount, then a citizen unit in the game is to be removed by game setup. This represents society's tendecy to have emmigration or a low birth/death rate.
If the population is higher than citizen amount, then a citizen unit in the game is to be added by game setup. This represents society's tendecy to have immigration and a high birth/death rate.
BIRTH/DEATH RATE:
The game file does not determine birth/death rate. The rate "users" enter/leave the game through the website forums determines birth/death rate.
EMMIGRATION/IMMIGRATION:
The game file somewhat determines emmigration/immigration. This involves defination of civilization which can be worked on.
--------------------------------
That's just basic population rules. More other Civ4 elements can be altered to fit this game. Notice though how these rules would be straight to the point and meant to make the game fun and , and of course they would be altered a lot from this to have universal terms, etc. Note, though, that rules aren't interferring how each civilization can adminster how family units are organized. This recaps the previous comment on your idea that each civilization should be allowed to structure and govern their own civilization to how they see fit.

Now to the website part. I have enough knowledge of creating websites and adminstering communities to put something like this on. It would need its own website. There is so much that this project would need that a simple addition to CivFanatics forum just wouldn't do. I am totally up to do something like this, including paying and managing the website. Since I am new to the community, though, I don't plan to get involved with the specifics of anything. I'll oversee it, fund it, and own it (for non-profit reasons). I do not wish to run it. If you think you would like to take the idea to the next level, let me know. Thx.
