So far I am pleased with the lay out and potential of diplomacy. I like the civ4 type diplomacy as it worked and was popular.

Some things have been mentioned already that need work and I can't add that much to it for now. However I think techs should be high lighted based on there specific tree. Red for warfare etc. Also possibly a small number or indication on specialization techs, as they are useless to a AI by and far, and are increasingly harder to comprehend what I'm selling as the more techs I research and trade.

I don't want tech trees but could they be only for tech trading, would enjoy that? Like you can only trade techs in your age, that would solve alot if not all previous trading abuses compared to the functions of the current system. Upgrading improvements could be the same way. Consider it at dinner will you. ;- )
