Another reaon phil/ind is overpowered, amazing access to it's fast buliding. It is long way off on the tech tree to forges and universities relative to other trait's fast buildings. Ind trait allows you to get the oracle (rarely to be beat as ind) so you take metal casting for fast forges (No other AI will have forges for a long while, even other IND leaders). Shoot for a great engineer if you can get him (fast being philosophical) and save him for the Great library. Tech writing/alphabet/literature. Build Great library with the engineer (still pretty quick to build with early forges if you have to) in a virgin wonder city, quickly build the national epic and spit out great scientists. Bulb Phil research paper, bulb most of education, finish teching education. My guess is you can have forges AND universites in most of your citieswhile most other AIs are just starting to build their first forge (unless you have trading phil or metal casting). Seams brutally overpowered, not including the fast wonder GPP's and Phil trait, even if you only get the oracle and GL. Add the Pyramids and it's way overpowered. Ind and Phil are more about fast forges and universities which other AI's will not have access to very early.
