I just downloaded it and I've got quite a few complaints. I don't mean to demean your hard work, so let me offer some constructive criticism:
1) I don't very much like the quadruple damage thing. One hit and people are dead even if they're wearing armor, horses ride around the battlefield like motorcycles or racing cars. A lot of different armor types had their armor values doubled for seemingly no reason and a lot of weapons had their damage tripled while some seemed to be only doubled.
2) The highest level Islamic cavalry troop type, Sipahi,
has no horse. A Sipahi should have a Warhorse, Lamellar Armor, Guard Helmet, and plate or chain boots.
3) It seemed that the Islamic troops you made had a very limited selection of weapons. The only ones I saw were Scimitars, Nomad Sabres, Spears, Battle Forks for Saracen Infantry. In fact the Muslim troops used a wide variety of weapons throughout the Crusades, including Glaives, Lances, Axes, and Spiked Maces.
4) None of the Islamic soldiers I saw were wearing Lamellar Armor, which was commonly worn by Islamic soldiers seeking something heavier than chainmail.
5) All the high level Islamic soldiers were wearing chain hauberks and had spiked helmets. The highest level Islamic soldiers, like Heavy Janissary Infantry and Sipahi
should have worn Lamellar Armor and Guard Helmets instead and rode Warhorses if they were cavalry.
6) It seems that you gave most mid-level Muslim troops Linen Tunics when they
should be wearing Padded Armor instead. Nomad Caps, Steppe Caps, Segmented Helmets, and Helmets with Neckguard should have also been worn, as well as leather boots by these mid-level Islamic soldiers.
7) The basic Islamic peasant, "Follower" has no clothing other than a turban and a pair of underwear. They look like Indian beggars with swords, not Arabs. Muslims would have considered it extremely immodest to go around wearing skimpy clothing, and the standard clothing for a Muslim peasant would have been a white or sandy colored robe. The Linen Tunic comes close but the Coarse Tunic looks the most like what a Medieval Islamic peasant would have worn.
None of the Muslim troops in your mod had any facial hair. The majority of Muslim men, both now and in the past, had beards or mustaches.
9) Gazis and Mamluk Skirmishers have no shirts on. Like I said before, Islamic troops would have never fought or walked around without shirts on, first because it would be considered religiously improper not to wear a shirt (and very impractical in battle!) and secondly because the white, grey, and sandy linen and cotton robes Muslims wore and still wear protect their bodies from the rays of the sun.
10) It seems to me that the Christian troops are mostly from the Vaegirs, who are modelled after Vikings. Vikings did not participate in the Crusades. The only Vikings that were in the Middle East during the Crusades were the Varangian Guard, and they fought as mercenaries for the Byzantine Empire and did not fight side-by-side with the Crusaders themselves. The Swadian soldiers are what the Crusaders would have looked like.
11) Mamluk Skirmishers and Beduin Archers should be replaced with each other, since the Beduins were nomadic tribes that would occasionally fight for the Arabs as light auxiliary troops and the Mamluks were professional warriors. In your mod the Beduin archers have chainmail and a Spiked Helmet, but in real life they would have worn nothing more than the standard white/sandy robes or padded armor at most.
I'm sorry to be so critical of your modification, because I know you tried really hard, but I've got a few questions for you. What country are you from originally, because it seems like English is your second language? I'm guessing you don't know much about Medieval Islam, the Crusades, or the Arab world in general? How much have you played your own mod?
And one final thing: I really wish it was possible to separate the Turks from the Arabs, because they both had different styles of dress, different cultures, different styles of warfare, and different weapons and armor that they liked to use, but unfortunately this mod allows for only one faction to represent the Muslims.
Just for your information, anything with the word "Janissary" means the elite Turkish soldiers, anything with "Mamluk" means the elite Arab soldiers, and both types of soldiers were usually slaves that were formed into a military unit. The reason the Islamic kingdoms formed military units out of slaves is because often they could not rely on their own citizens because their citizens were more loyal to the local clan or tribe than they were to the Sultan or Kalifah, but slaves had no loyalty to anyone but their masters, epsecially if they were treated well.
I haven't played the Christian faction yet, but since their armor and weapons were already programmed into the game, I'm sure there were a lot less mistakes and I'm sure you did fine with them. This game was made mainly to be two different Christian Kingdoms, one regular European, the other Viking, fighting each other, so I realize the difficulty in creating a unique, Muslim faction, but unfortunately your mod still needs a little work.
