I agree with a lot of what Morindin wrote. There are playing style issue differences, but I see the comparison of MTW to RTW in roughly the same light. There are fewer, "Oooohhh! Aaaaaaahhh!" units in MTW while RTW is full of them (to its detriment.) Ironically, in RTW the foot sloggers, the bread and butter of warfare of the time suffer for this. They become bit part supporting players in my armies where I regularly make decisions like, "I guess I better build/buy two or three infantry units to work the seige equipment." The battle UI in RTW is simply cludgy. That would be less of a problem if battles were fought at reasonable speed. When the enemy begins its charge, I have to pause to issue commands. Otherwise I have almost no way to counter charge.
