well, at least thy snuck a little Milanese into the game in the form of steel. though, only vaguely Milanese. the helm was more a a barbutta than anythn else.
more than anythin, the lack of close-face helms disturbed me.
I wasn't happy about the lack of closed helms either; without KotN or SI, the only useable closed helms were the Daedric, Bound, and Dwarven. However, such helms would be more practical in Morrowind, where they'd grant face protection from the ashstorms.
But overall I liked the style of the TES IV Imperial armor better than the TES III Imperial armor. It looked like a combination of Greek and European. But I'm just not a big fan of Roman-style armor.
