Is it possible to set up an option where a player can add another player as a buddy in-game.
The idea behind this is that if someone is a buddy then one cannot attack that player. This is in effect a personal non-aggression pact. Even if two Alliances are at war with one another if two players on opposing camps are buddies then the would not be able to attack each other.
Also this will allow someone to protect one's Buddy by protecting them in an attack by sending troops to their Tambo (once the Tambo feature is developed).
I do assume that a player cannot attack a fellow tribe member.
