I seem to be necroing posts so... I really dig this idea. While yes I value CRE for rexing, something that builds more culture seems right. 10% is modest enough but rewards culture building. Could probably keep the base at +2 with the +10% and it still would be fair? I will say though, Pericles’ UB, the Odeon, is half-priced as CRE leader and gives +2 , +3 , and 2 Artist slots all at a crucial time with an important tech. Not too shabby especially towards curltural victory. IMP seems in real need of upgrade as many have pointed out.. Settler bonus seems much less useful after early rexing and it only bonuses s not s. Both should get the bonus. Another good suggestion has been adding a non-military imperialistic benefit, i.e. economic? Perhaps half-price Customs Houses? Or domestic trade routes 2X in value?
