I tried to manipulate AI factions by giving them 1.000.000 mnai.
(Not on console, via diplomats)
What they did?
They sat, womanized, boozed...
But no expansion.....
No idea on M2TW but RTW AI just hires mercenaries with money other than it. money script is useless to manipulate them. Just leave the mercenary pools to them that may make them more agressive and of course not against A.S.
