Is there a mod that lets you make and break alliances between players?
I think that's a standerd part of the game. When you set up a game you can pick either alliances or teams. At east that's how it's set up on A1.
In Armada II the alliances are permanent. I ask this because as playing as the Cardassians I want to switch sides against the Dominion like they did on Deep Space 9...
Dont most mods have the Dominion and the Cardassian as the same race... so breaking would be kinda difficult. Still it would be a great idea although i dont think it could be implemented due to engine limitations.
I loved playing AOE (Age of Empires) miultiplayer. Used to play over a LAN with a couple of friends with a few AI players. In this you could nicely change alliances. One game the AI game me a serious ass kicking so i ran some villagers over to my allies (human player) base and used my remaining resources to build up some defences and gather more. Told my friends i would work on his base defenses while he sent his armies out to take out the AI. Worked great until the game was close to the end where there was only the 3 humans left. The guy i whose base i was camped in was involved in a war of attrition with the other guy and both were really struggling for resources.
At this point i declared war on my buddy and all my towers (bombard towers as well, i was playing as turks) and a few elephants i had managed to build started tramping his base.
His face was a sight to see. I think he felt betrayed and expected me to declare an allied victory when the other guy was defeated. ;-)
