Firstly I’d like to point out I thought of this from Sleipnir’s thread (check link at end of post), so I want to point out a few of his ideas which would make my suggestion work. The stuff in square brackets is what I added/edited.
“Alliance leaders can declare peace or war with an alliance. These relations will override personal relations (check alliance rel first, if neutral use personal rel). If alliance A declares war, everyone in alliance A will be at war with alliance B despite what the personal relations may say. Alliance B will still be neutral. The alliance leader of B can choose to return the declaration, starting full scale alliance war. However, if he doesn't, and [if any 2] members of B rack up a total of [10] or more attacks on A [(within 24hrs)], the declaration will automatically be returned. So no hiding on neutral unless you really are neutral.”
My suggestion:
You can capture the other alliances units, which are then held in a reserve, until a winner or a draw is declared, then the units will be redistributed depending on who wins. To find current wars a list is created with all current alliance wars posted on it (can search by power, alliance name etc).
Fairness and other restrictions:
Where the alliances have at least 1/3 of each others power OR 1/3 of each others units they can declare all out war, if the other alliance declares all out war back, the miner capture system is introduced. You can still war with a stronger/weaker alliance just you can’t capture their miners or get any recognition through a war wins counter for doing so.
Gains and losses:
You can capture other players miners/lifers as prisoners of war, you get around 0.02% per attack for miners, 0.002% for lifers. with 1000 attacks, 15k turns to you take less than 20% of their units. The rates can be raised up to 0.007% per 15 turn attack, with 1000 attacks it is around 50% of their miners taken, the rate for lifers will always stay the same at 0.002%. for the rate to be raised to this max level (or somewhere in-between), both alliance councils (explained next section) must choose a rate, ie alliance war council A wants 0.002% and alliance war B wants 0.007% then the rate is as the lowest amount, ie the 0.002% of attacks.
Alliance war councils:
A war will start like this, alliance A declares war on Alliance D, if alliance D declares war back, the war will be placed on the war list. At that point if alliance A is friends with alliance B, alliance B can join, by a join team a or team b button, if they don’t make one side have 3 times the units AND 3 times the total power. Alliance A then has the option of accepting alliance B as part of their team or they can reject alliance b and they are removed from the war and have no place on the council. If they are accepted into the war team A will have a alliance war council consisting of the alliance leaders of alliance A and alliance B. Alliance C can also join in with team A as long as they don’t make one side have 3 times the units AND 3 times the total power. Alliance A and B can then vote on if alliance C can enter the war, Alliance A’s vote will always count as 1.1 because they are one of the initial parties in the war, also it will prevent hung votes.
Prison camps:
Prison camps are a new section on your main menu (command center) so you can view units lost and captured. Basically on the main screen u can see, the miners/lifers u have captured, the miners/lifers u have lost. Also in alliance management u can see your alliances total captured and lost, and everyone on your alliances side (if more than one alliance is involved per team) also has a counter under alliance management.
What happens in the event of a draw or winner?
Also Sleipnir wrote “Some sort of record will be kept of alliance wars.” This is a great idea, this can be found in the alliance page when looking at the alliances. However you only have one alliance war for miners 2 weeks after the last one has ended to prevent pointless wars for wins, if wars are declared just to increase the wins, all wins should be removed from the alliance by the game admin.
Also as well as this some other things should happen.
All relations are set to peace for 24 hrs, then after this period they are reset to neutral, which can then be changed 24 hrs later.
The losing side does not get marked with a loss if they surrender within 1 week.
In the event of a win:
Each player gets 80% of the units they have captured, miners come as miners (so no uu is left out), lifers as lifers. 80% of the miners/lifers they have lost to the other alliances also come back to them, unfortunately due to poor conditions 20% died.
The other side does not get any units back or any of the units they have captured.
In the event of a draw:
Both sides get 80% of the units captured or 80% of the units captured are returned, the rest die. By default the units are returned unless both sides agree otherwise.
Ways to win or lose or draw:
1. alliance war council members from both sides elect a benchmark amount of units stolen which when reached (a handicap can be given to 1 side if desired), the alliance is declared the winner.
2. one of the alliances surrender
3. both the alliance councils decide to call the war off, this results in a draw
4. surrender under conditions such as, they get 50% of their units back eg 0.5*0.80(max that can be retrieved).
5. if the war has gone on for over 3 months, it becomes a forced draw, unless both sides agree for it to continue. In the event of a forced draw only 60% of units are returned instead of 80%.
