Non-binding promises

By Civo, in Sid Meier's Civilization: The Board Game

Hi to all

I have being playing the game with friends over the last 2 weeks and we are having a lot of fun. We argue though on this topic. What is a non-binding promise? Is it simply a promise that you don't have to keep? Can you give me some examples from your games please?

Haha, exactly.

A non binding promise can be everything from a non aggression pact to the first born child or a cold beer.

For example: "If you give me 3 coins, i don't attack you for 5 rounds" or vise versa.

You can't give coins.

Played yesterday, some of the promises:
Romans gave Egiptians some trade, so that they will atack my Russian flag.
Egyptians will use the technology (or was it culture event) that gives 9 trade and will give the 6 trade to a player that will give them 3 back.
