These horsey things you speak of, tell me, player of the last 3 XOTM games, what are they? Thin elephants perhaps, Only barbarians and non-believers seemed to posess them. Neither the Spanish, Arabs or Americans were so blessed to ever witness them until quite late in the adventure.
Being that this is a COTM, the extra food for the Agricultural will help jump start the growth. Among the AI only the Dutch are AG, but their SEA trait is wasted on Pangaea.
I will probably settle in place and go warrior ->warrior->settler-> granary-> settler. Research for the Republic Slingshot at maximum. It should be quite a race for CoL and Philo. Hoping a couple of the AI take a non-direct route to give me a chance at a free Republic. The Map Making distraction is my best shot.
This is one of the four natural tribes (Rome, Byzantium & Sumeria the others) that I have not won an XOTM with yet, so it's a must play.
