Diplomacy Exploit

from GalCiv3 Forums

There is a huge exploit when trading with A.I.

A.I. will happily trade all of his empire (except for his homeworld) for a hefty amount of credits per turn.

So as of patch 1.01, you can easily win any game by just buying everything from A.I. and then declaring a war (therefore breaking your promise to pay) and killing him with his own ships, while not loosing a single credit. Same goes for offering trading and luxury resources. In my opinion, A.I. should not give anything immediate for Something-Per-Turn. At least, not without Non-Aggression pact for the duration of the deal in effect. Sorry if this is a known issue.

Thanks for posting your issue. Do you mind sending a save before this happens to support so I can have a better idea of what is going on? How many planets did it take until the trade was flipped to a yes? Which faction were you playing as? If possible, steps on how you were able to reproduce this issue would be awesome!

I believe there is a misunderstanding. It's not the same issue as in this thread https://forums.galciv3.com/466429/page/1/#3556643 .

It's just the case of offering A.I. like 100 000 bc per turn in exchange for his colonies and ships, which he will take gladly. And then declaring a war on him immediately after, breaking the deal in process. So as a result you will be left with everything he had, while not paying him anything. I was playing Yor and Altarians if it matters at all. I do believe it'll work like this in any game and it's just an oversight in trading with A.I.

I was going to post this same issue. All you have to do is put everything that they can trade on the table, set up the necessary credits per turn in exchange... accept the trade, declare war... And you win. This isn't an issue in single player since I just don't do it.

A suggestion for a partial fix is that the credits per turn be capped in some way by actual max income (i.e., if 100% economy produces 500 credits per turn, that is the most you can offer in trade) and that the AI be less willing to trust credit per turn trades depending on their relationship to you (i.e., the less they like you, the less they trust you to repay credit per turn deals).

I'm not sure if these two suggestions would completely eliminate the exploit, but I think they would help it become less game breaking.

Yep just tried it out. Got 80 % of the colonies for free. After declaring war on each of the players
the deal was nonexistent so my 100.000 BC per Week did not have to be paid.
pretty insane could not believe it first.
