Yes, I suspected such a thing
I did indeed start one more run, this one as Pericles, and I disabled all victory types other than score. I did however forget to change the turn limit derp. But I drew such a good map that I stuck with it. Had eight cities planted by turn 200, so it's all going very well. The last 150 turns will drag by haha
Pericles gets +5% culture per city state that he is suzerain of. With barbarian clans mode on we end up with like 40 city states, so this is a powerful bonus.
