while searching an alternative of the easy Inca rush I suspected some of the civs with chariot specialst could be better, that is why I tried to generate on deity a map with horses in the first city borders of Kublai Khan for example. The experiment included over 50 map starts and several hours - boring but still there were some results: 1. In all the generations there were not a horse resource in city borders. 2. In all generations there was no horse resource in the first city borders of other civs too. 3. when there is a lot of land and few civs - there are more horse resources, when there is less land and many civs - there are few horse resources and even in some cases NO horse resources at all. 4. When you have duel, tiny and small map with 18 civs the chance is 99% that the map will NOT have horse resources. 5 - When you have 18 civs on a standard map there is 1-4 horse resources but nowehere near any of the first cities. Experimenting with all this conludes horse civs dont have chance on deity. Horse spawn on higher level is striclty linked with number of civs and also a rule not to be in or close to any first city borders - denying advantage to any civ.
