This sounds extraordinarily complicated. Is this a game where we eliminate each other until a winner is found, or does it go on forever as if it were a SEN Cybernations?
I'd like to see more rules regarding combat, where resources & population come from, how to manage them, etc. This won't be a realistic simulation at all because every country IRL didn't start at the same time with the same stats. As for the rules about war: how does a person win, what we can attack with, does losing equal total destruction or only partial... etc...
I have thought of this through for a while, it is indeed complicated and requires a very reliable (I will do the math and thinking, I am clearly not biased) and time consuming host, me. For now, every player has an entire week to declare their moves and actions by posting (After all, everything is PUBLIC), or sending me a private message for hidden plans against another country. Players can use communication through any way, but if they are to interact and help a nation secretly (For example, Germany wanted Mexico to join World War I, the British found the message and told the United States), then they must send me a private message and I will forward it to the player they will seek to interact.
Regarding combat, trading or asking workers to work on resources, will supply the Military. The training will be costly both money and time, if you want a stronger Military. Each group sent in combat must be fed, supplied, etc. otherwise their exhaustion will be the downside of the war. Population per country will be set to default in 20,000,000 while the Military has 500,000 available. Players are asked to conserve their troops, 'propagandize' (Artwork + Quote required, bad picture or bad quote means no joining) for civilians to join (Or force join), and may split its numbers to attack certain territories but remain some for reserve. Usually in the first battle (Day one/Month one), hundreds to five hundreds of civilians are killed unless Military defenses were set up. And it is recommended for players to send in big numbers to each assault/defense. Players may sign treaties, some are forced to not sign it very early.
On winning, the opposing players must declare surrender (They can't surrender if it isn't appropriate, that will ruin the game) in order for you to win the game. Another way of winning is if all of your alliance had conquered every other country. Another way is a treaty. And another way is probably total control, forcing players under your command (Such as France taking over countries in the Napoleonic War).
Losing can mean surrender, revolution, another country controls your country (Until liberated by another country), etc.
I believe to keep the game a little simple, the time period should either take place in the 1700s or 1800s because it is just ground army, cannons, and navy.
None.
