Anyone who thinks that striving for historical accuracy would be boring is simply wrong. There are far more intersting people and soldiers in history than CA represents.

However representing them historically would reflect all factions weaknesses as well as strengths. And at the time of the Crusades, the Saljuq's training of their ghulams had declined. The Saljuqs (calling them Turks is silly, there were many Turkic peoples in the world at the time), would not be an easy faction to play as, mainly due to both the Crusaders and the fact many of their own men often were mutinous.

Oh, and 600,000 men is an insanley large number... now way could they have fielded that many men.
