The game runs terribly on my computer in the fourth installment.
But for me personally, the shock when I first played the "fourth" installment was the elf-Indians and the elf-Negroes on the map. Thank goodness that at least on the screen, the armies of the Ancients looked like proper Eldar, and not a mixture of Uruk-hai and Haradrim. What reconciled me to this situation was a remark from one lady, who suggested that this was simply a camouflage tactic on the part of the Elves to confuse the enemy).
