I wouldn't bother playing anything other than the British Isles.There are tons or rivers and huts on the mainland and a human will dominate fairly easily,fairly early.
With this in mind,I tweeked the Isles a bit and set a favorably resource seed.
Then I went around changing starting spots to more historically correct sites making sure to plant them in the middle of specials.
China I put in the middle of 4 wheat.They built Leonardo's in 325bc!!!..very impressive.
