Yeah, that's why the AI civs are called 'ATMs' at higher levels (at lower levels, they don't have the gold but it didn't matter much anyways). I agree with Pilgrim in that those that are interested in efficient strategies at higher levels will compensate, as we have done when other strategies have gotten nerfed or changed. From all indications thus far, Pilgrim and chazzy can confirm, early growth and science will still be the primary drivers for all victory conditions even though science appears to have been re-balanced a little.
