I agree Greek UHV it's too easy, and also to not have the Alexander's conquests. Map all the Ancient World it's a neat condition, at least a freshly new one. It will make you to make a lot of balance in diplomacy,because you want to have Open borders with everybody. But AIWars will be there to make your life impossible. I like another possibility, which would be:
3. Have 2 trade agreements with Egypt, Persia, Rome, and Babylon by 300 BC.
That will make you go conquering a bit, to have some resources to trade with, and also will made you to make some diplo work. Explanation? Greece did explored a lot of land... but not for free! They were there to sale whatever other civs wanted for. Greek became the "common" language of the Ancient World because greek merchants were just everywhere.
