Well, I want to see if the turn can be fixed. Lemon, I might add that I have something special- the ability to build an archery range and more in a short timeframe. But anyway, Vanigo, am I good on the error? Irony, I won't take your city. Same as before- drive right by it.
Meh, all of you can build counters in a short time frame, but the main use of the pegasus knights will be raiding land and taking isolated cities, where it will be hard to have a appropriate amount of forces, and hard to catch up with them as well, dervishes or cavaliers will deal with the main battles.
The only true counter to them is dragoons (calvary so they move fast, and very high damage so they can fight them with only a slight numerical advantage without any problem), but they take quite a long time to get to unless you were planning on it, and since they aren't flying (and don't have charge), they will take charge damage and won't be able to follow over water. Calvary archers also slightly work, but they are a bit too weak to do it without overwhelming numbers.
Irony, I would recommend you get involved and save Sheb (your standing guard will almost certainly be enough to make sure that doom doesn't push through and take Sheb's city, since he will want to defend his own, which is also necessary to get reinforcements to the north), otherwise Doom will get a bit too strong (since odds are pretty good that he will win the battle at the city a bit farther north as things are going now, and then will probably be able to finish taking the rest of Sheb's cities). At that point he will be pretty easily able to take your remaining city on the continent (since it will be 6 cities of peacetime production and near unlimited stone against your 1).
Also, hurry up and post Sheb/Doom.
This is a concern, but I'm actually more concerned about Sheb courting foreign powers.
I don't think that that is really that much of a concern, Doom's incoming navy will stop Kash from landing, and our real focus will still be on our island.
Plus, my main goal is to stop one of them from becoming too strong, I don't really want Sheb taking over Doom (even if Me+Kash each get a city), since he would pretty promptly turn around and eat both of our cities up (followed by your cities on the mainland).
EDIT: I should note it might be different for kash, since he is only about a turn away from Doom's cities via carrack, and could probably fight near evenly if he ported enough units over there, whereas it would take 3/4 turns for one of my units to get over to a city.
