Excellent way to control the AI's expansion without FD

[Fluvius Camillus]

He is probably meaning you could FD them protectorate instead of buying them with 1million.

As an empire builder I usually reach the 1m, but will take a while though....

[MarcusAureliusAntoninus]

Having protectorates is not advisable. They are a bit bugged and the money script really messes up the whole premise.

[Maion Maroneios]

I second this is way too much of a hassle. Better use FD, IMO.

Why do you want to subdue the AI?? If anything, I always wish the AI was stronger. I never truly had a real challenge in my current Romani campaign.

I do this mainly to keep either the Ptolemies or the AS from too powerful. It's to protect smaller states like Baktria, Pontus, and Hayasdan. I don't do it to enemies that I'm actually fighting.
