I'm playing the original AOW, Cult of Storms campaign, United Cities map. Interesting that Frostlings allied with Elves but not with Halflings and when a combined Elf/Halfling attack killed my Orc allies, Frostlings broke the alliance. Managed to get them by my side with enough offerings of Jew Gold and turns out I saved them from being killed by a huge army of Halflings.
Funny. I never ever even thought of bribing the neutrals on maps with allied victory enabled, I always just destroyed them. As in, the thought never even occured to me. I guess crushing all opposition always seemed like the natural thing to do. I think like a barbarian.
