If there's a proper earth map with real starting locations, I'll be Songhai. Try to take out Ramses fairly early than turtle in Africa for a while with the Suez chokepoint, meanwhile I'll be taking out as many barbs as I can find to collect the gold bonus, which I will use to either rush units to start taking out (Babylon?), Persia, Ottoman, Greece, Arabia, and Rome, or I will use to rush some territory and culture out.
If there isn't a proper Earth map, I'll play as Siam, assuming I like what his racial bonus is.
