Most were answered already, but:@sampsa, three questions, please.
- Why Barracks but no Ger (Stable)?
- Why go for the northwestern Horse when the southeastern Horse lies near a river?
- If your game were continued (though I do not ask you to continue it), would Construction and its Catapults halt your Keshik-led (Horse Archer-led) conquests? Or would you expect to fight through even Construction and Catapults?

2. NW horse has food, which is very important. Running for the SE-horse with 3rd city is possible, but the wet corn spot to the W is too valuable to skip IMO.
3. Catapults are not an issue at all. Massed spears and later longbows can be annoying. On this level the AIs seem to expand very slowly, so they can't have many units either.
