Is hard, ok, start again, the Ai can start be a ally or vassal, then what happen in 2v1? The vassal can rebels and be Enemy if your enemy is win the battle. Or if them are increases their power(military or economic may be) And low their loyalty. The ally can be Neutral or turns a Enemy even much easy to betray you than a vassal. But this don't happens in locked teams. If you turn an Ai (Enemy) into a Vassal in 1v2 the vassal can't riot or turn enemy it's defeated automactly if the loyalty is low. Obviusly this happens if the Ai. Started as Enemy. How turn a vassal, if the Ai offer to you resign. Now the other snow ball can be when are more than two Ai. for me in all modes. Multiplayer and single.
