Hi Mara,
That's a great suggestion and is on the to-do list already.
We'll be releasing a variety of new alliance diplomacy options, running from:
War -> Truce -> Neutrality -> NAP -> MDP (Mutual Defence Pact) -> Confederation
It's anticipated that these statuses will *automatically* draw alliances into war if the criteria are met.
Examples of what a Mutual Defence Pact would mean:
Example 1
Alliance A and Alliance B have a mutual defence pact.
Alliance C declares war on Alliance B, and this will automatically declare from Alliance C to Alliance A as well (who are coming to the aid of Alliance B).
Example 2
Alliance A and Alliance B have a mutual defence pact.
Alliance B declares war on Alliance C... and that's it. Because the act of aggression was from Alliance B, Alliance A is not drawn into the conflict, as the pact between Alliance A and Alliance B is defensive in nature.
Confederations will draw all partner alliances into a unified action (and we do understand that this will mean people will be much choosier about their confederation partners).
It is envisaged that in the circumstance where an alliance has conflicting pacts, they will not automatically declare anything.
Truce would be an intermediate status from War - a cease-fire of sorts that could be broken (details TBC).
Any other ideas for diplomatic relations, though, would be welcome.
Regards,
SC
