Quillan, how are those not good deals for a single territory? Yes, it has gold mines, but the population is measly, you get up-to-date on tech, and 10000 ETW-bucks!

I think one of the problems is that the player simply doesn't lose, at least not us hardened veterans of TW. IRL, nations would trade around territories quite often, especially after marginally won war, which we don't really have. As for the frequency of these offers, the AI should have decided a set amount that they wish to escalate the deal with, instead of several very similar offers.
