After getting to like the guns in Vanilla, I've started to wonder if we couldn't, or shouldn't, just up the end date past 1400 to a later date. One advantage with the middle east over Europe is that generally things were a little bit slower, or a little less dramatic, in it's change. I've seen Indian armor from the 18th and possibly 19th century which features metal armor, and seen Iranian armors from the 19th century which seemed to include mail. Obviously we'd not go that far ahead, but what about up to 1453, the fall of Constantinople? Or even to maybe some time in the very early 1500s?
There's only one real reason that I'm suggesting it, and that's gunpowder units. http://homepages.ihug.com.au/~dispater/handgonnes.htm Tells us that gunpowder hand-weapons, more accurately hand cannons, existed since the 1300s in Europe. It may have a presence as early as 1281.
We also see that by 1400, it starts to steadily improve:

Take a look at this image, for instance. And I don't know what the deal is up with that guy's orange beard.
Both mameluke's are pretty much already in the game. Their helmets are, their mail and plate is. and the #2 guy is still using a bow. #1's arms on the ground are the same. #3 is a handgunner whose got mail on, along with his gun, which is pretty much the one from Vanilla. Now all three are from the 1510s, with it possible to fib that date to something a little sooner (I'd prefer to end at 1500, since I dunno what comes afterwards that would require it's extension).
That's egypt. The Turks as we know have a good reputation with firearms. Only problem is that from osprey, it says:
"Janissary regiments trained regularly and in the early days their weapons included bows, slings, crossbows and javelins. Some hand-guns were adopted during the wars against the Hungarians (1440-43), and more Janissaries were given firearms after the defeat by the Mamluks in Cilicia (1485-91), but not until the end of the 16th century did the majority have tufek matchlocks."
So we see that at least by 1440 were hand guns being used, and by at least 1485 would the Mamlukes probably have the arms that African gunner has.
As we look further for historical detail, the question of gameplay and appeal comes into mind. Would we want gunpowder infantry to play a role in later era warfare? Would it require very little work, likely just modeling a firearm in for certain infantry meshes, perhaps making one or two new ones?
Would it find a way to be acceptable for factions which were eliminated by this time? Egyptians used them, Turks would have, and I have read (Not in osprey) that the Afghans really took off with the gun (Giving them a distinct advantage against the horsemen that once forced them to take to the hills), so the Ghaznavids and Ghorids would be likely to adopt them. India too. But what about the Abbasids? Georgians? Armenians? Byzantines? KoJ?
