Can we get some info on what you've actually agreed on? Ghazkull's claim that you weren't holding up your end of the bargain is very important to this issue. And uh... not me being curious about your shady deals- that has nothing to do with it, yup.
We agreed on a two part deal:
Part 1: I give him tech, he gives me votes. This took place immediately.
Part 2: He gives me services that shall for now remain undisclosed. I give him a reward that shall likewise remain undisclosed. The payment was to come later.
I feel like he has not followed through on his promise of services and is in fact doing the exact opposite of what he promised so I feel it would be foolish to deliver the promised payment. He feels as if he has rendered the services and is now free to change his course of action. We unfortunately did not specify an exact time frame at which his services would be considered finished however the period of his compliance has been less then a complete game round. As such we both consider each other to be in violation of the second part of the deal and it appears to be null.
Ghazkul feels that since the second part of the deal is null he is freed from his obligations in the first part. I however feel that the house rule specifically prohibits him from changing his votes once pledged. "A future favor" was not one of the terms agreed to in our in game deal. As such I feel that the rules of the game prohibit him from changing his vote regardless of whatever the diplomatic situation between us is. Even if I were to declare war on him the house rules require him to honor his promise.
