I recently started playing with Ancient Ruins turned off and I like it a lot better. With Ancient Ruins turned on, I have to constantly worry about what the AI is finding, and if I don't get a 1pop, scout upgrade, and free tech (playing on Prince), I feel at a serious disadvantage and end up wanting to restart the game. Who needs that? So I turned it off and find that my play is improved as a result. I can focus on exploration for the right reasons, and never have to compromise early by being forced to build a scout and leaving my capitol and workers open to barbarians because I am out scouting for ruins. Anyone else turn them off? What are your reasons for playing with/without them?
