Combination of following wonder effects Expanding Culture - increases assimilation and conversion so integrated culture does not care as much about AE Government Traditions - province loyalty increase Conquering Traditions - reduce AE impact. Wonder built asap in 480 or so Then got all tech reducing impact of AE (not necessary increasing reduction rate) Then got Militant Epicureanism innovation in religious tree allowing desecrate other religions temples for plus 10 stability. Stability at 60 or more reduces makes provinces more happy. Then combo of uncorrupted governors and temples and grand theatres resulted in only single province rebelling next to Carthage Never had AE more than 100 and new provinces were being assimilated faster than dropping loyalty so even rarely later had to use harassment policy.
No. i had 3 wonders only. First was with Expanding Culture for conversion and assimilation speed Government Traditions for loyalty and corruption reduction Conquering Traditions for AE reduction and war score cost They affect whole empire. Second one was tax and commerce for money whole empire Siege tradition for faster sieging. dont remember the rest but they were build just cause. Then i build in five corners for achievement but that was at the end.
