I'm not well versed in the DyP mod or even on AW games in general.
If it is your first AW, you might want to consider an Oscillating Warfare game (I think that is how it is named.) In this variant, you plan to conquer the world, same as AW, but the order is a bit different. In AW, it doesn't matter who dies when, as long as they all die. In this version, they have to die in the order you meet them.
It works like this:
On turn 10 you meet the Arabs. Trade, if possible, on turn 10, but by the end of turn 10 you must declare war.
On turn 20, the Arabs are still alive and you meet China. Peace with China is okay, so is trading.
On turn 30 the Arabs are dead. You have one last chance to trade with China. At the end of turn 30 you must declare war on China.
Repeat as needed.
Of course, you can let the Arabs stay alive long enough until your forces to attack China are in position to attack. (Life support. What a concept!

)
Some AW Tips
In AW the key, I think, is to expand strongly. Your cities, especially early in the game, will be attacked. Perhaps not your capital, but the others. So try to build them on hills and have them make walls. Walls have no upkeep and add to your defense. The AIs will outproduce you at first, because of their cost discount, but you can plan and deceive the AI. In this case, Quality of execution will tend to beat Quantity of troops.
Early on, you will need defenders, which tends to be a rather rare occurance in C3C. Spears and Pikes will blunt the attack of the AI (and the AI will attack). You will need some fast units that can attack out of your cities to kill the crippled stray units and then retreat back into the city before the AI kills them out in the open ground.
After a while the AI output will sputter and slow. Your cities will be better managed than the AIs and you will handle your troops better, so you can slowly begin to go on the attack.
AW SGs
There are several AW succession games in progress, but let me point you to my first one,
>>HERE<< , where we were the Russians. This was the first AW for everyone involved, so the discussion of what we were doing and trying to do will be more important to you than the battle results.
