I have a simple game idea. It would involve only a few things, perhaps two forums and a moderator, or referee.

The game is the posing of this hypothetical situation:

-> You are a space navy cadet. Your final project is the design of a fleet. Your fleet is limited by these factors.

1: You only have 100,000 tonnes of material.

2: You have access to the different types of materials available on earth in the quantities that can be found in the crust, less than 1km down.

3: You may only design 5 ship types. Each type will be assigned a classification.

4: Each ship classification will have an artificial intelligence installed on it.

5: These AI's will be quite stupid. They will not plan, they will not follow complex lists of commands. They will either attack, defend, refuel, flank, observe, rearm, and repair as they have been designed.

The fleet that you design will be pitted against the fleets of every cadet in the program in 1 on 1, 1 on 2, 1 on 3, 2 on 2, 2 on 3, and 3 on 3 combat simulations.

You will be awarded points based on

1: Cost: On a scale of 1 - 100, where 100 is awarded to the cheapest fleet, and 1 to the most expensive.

2: Effectiveness in Attack: On a scale of 1 - 100, where 100 is awarded to the fleet that destroys the most ships total

3: Effectiveness of Defense: On a scale of 1 - 100, where 100 is awarded to the fleet with the most intact ships and 1 to the fleet with the fewest.

4: Effectiveness of Co-operation: On a scale of 1 - 100, where 100 is awarded to the fleet that best supported and was supported by other fleets in multi-fleet combats. That is, that the win chance of other fleets, and the designed fleet rose the most when paired. 1 will be given to the fleet that lowered the chances the most when paired.

Now, I think this idea is fairly complete, and I would like to take it for a short test run, but I have no idea where or how to do that. Any ideas?

Also, yes, this was inspired by this thread: http://www.gamedev.net/topic/673666-fleet-composition-a-little-experiment/

What does that mean? What is it that you want to do?

I want to use a free system that is already in place to run a limited version of the outlined game.

Now, I think this idea is fairly complete

Computers don't have common sense or imagination to try to figure out what you mean.

start coding/ creating.

I think that you both misunderstand what I am trying to do. This is not a computer game. There will be no code. The gameplay will be discussion, talked out between the players and referee. This will play more like a tabletop rpg than a computer game. Really, what I am looking for with this thread is suggestions on where I can find a site that supports that kind of play, where the public can join and leave whenever they want.
