Since I am a team member of C2C all my games are within 1 day of being constantly up to date. I play Emperor on a standard or large map with default # of AI, all AI are random. Game speeds used are normal, Long, and Epic, with an occasional Blitz and a rare Marathon. Anything else longer didtorts the gameplay to badly for me to use as a Test game. NO Revolution, No Inquisitors, No Corporations. Standard Traits not the new set, No Combat Mods nor Size Matters, Multiple Religion Spread, No terrain Damage, Battlefield Promotions On, No Peace among NPCs, Reckless Animals On. etc. I am using these games to continue to tweak and adjust the Civic set. I have Greece as a neighbor in newest game and it has been a constant fight. He got Neanderthal Culture 1st so he sent waves of Neanderthal units. I happened to get Iroquois' Culture Units not long after. They have saved me from being overrun. And I had elephant in 2nd cities ring. We are the only 2 civs on our landmass and he has aggressively tried to cut me off from the main body on the "continent" we share. I have had to destroy 2 of his encroaching new cities or else. He still has more cities than I do though. By the time we will be able to cross the strait to the next landmass the Celts are waiting. That should be interesting. My experience with the factors I have posted give me a constant challenge.
