I think that the game will be so much rich if there are at least the same innovations that another very similar game chivalery medieval warfare.
I agree absolutely with this post about sieges

I think that destructibles walls, boiled oil; greek fire, many kinds of catapultes and onagres must be there.
And off course player must be able to take control of this perhaps like a horse.
In fact I am absolutely sure that the game will be incredible most rich if there are also war elephants and war camels...; that will be also historically acurate even if was not the case in middle europe.
the adittion of parhaps 2 news faction semblable to chinisse and hindu civilisation will be wonderful as well, even if they are not playable for the player...
so here same historical research with pictures, videos and information for my historical research on this topic

Nations in the East occasionally fielded cataphracts mounted on camels rather than on horses (the Romans also adopted this practice, calling camel mounted cavalrymen dromedarii), with obvious benefits for use in arid regions, as well as the fact that the stench of the camels, if upwind, was a guaranteed way of panicking enemy cavalry units that they came into contact with. Balanced against this, however, is the relatively greater vulnerability of camel-mounted units to caltrops, due to their softly padded soles on their feet, unlike the hardened hooves of horses.

camel archers
Camel archers are marksmen wielding bows mounted on camels. They took their popularity in the Crusades, used in Arabia, Asian and Eurasian countries. Saladin, the leader of Arabia from 1174 to 1193, was known, or rather believed to use camels as a substitute for other ways of transport, such as the more common horse.
war elephant
This is analogous to the Eastern cataphract horse archers mentioned previously, who carried both bows and lances, and alternated between missile and charge attacks as the terms of a battle dictated. The three to four men manning the howdah, including the driver, known as a mahout, were armed with sarissae, javelins, pikes or bows to harass enemy soldiers who attempted to close in and attack the elephants. The tough hide of elephants afforded them considerable protection, and the scale armor worn on top of this made them almost invulnerable to missiles such as arrows, bolts, stones and so forth. Cavalry were also easily frightened by the smell and presence of the elephants, particularly if they had never been exposed to them previously, which allowed them to be used as living, mobile fortifications to counter cavalry manoeuvres on the battlefield in addition to light artillery platforms.[30]

Detail of a cheirosiphōn
The portable cheirosiphōn ("hand-siphōn"), the earliest analogue to a modern flamethrower, is extensively attested in the military documents of the 10th century, and recommended for use in both sea and land. They first appear in the Tactica of emperor Leo VI the Wise, who claims to have invented them.[39] Subsequent authors continued to refer to the cheirosiphōnes, especially for use against siege towers, although Nikephoros II Phokas also advises their use in field armies, with the aim of disrupting the enemy formation.[67] Although both Leo VI and Nikephoros Phokas claim that the substance used in the cheirosiphōnes was the same as in the static devices used on ships, Haldon and Byrne consider that the former were manifestly different from their larger cousins, and theorize that the device was fundamentally different, "a simple syringe [that] squirted both liquid fire (presumably unignited) and noxious juices to repel enemy troops." However the illustrations of Hero's Poliorcetica show the cheirosiphōn also throwing the ignited substance.[1][82]
Grenades[edit]
Clay grenades that were filled with Greek fire, surrounded by caltrops, 10th–12th century, National Historical Museum, Athens, Greece
In its earliest form, Greek fire was hurled onto enemy forces by firing a burning cloth-wrapped ball, perhaps containing a flask, using a form of light catapult, most probably a seaborne variant of the Roman light catapult or onager. These were capable of hurling light loads—around 6 to 9 kg (13 to 20 lb)—a distance of 350–450 m (383–492 yd).
