Right. When I was younger, the museum had an exhibit with armor and swords. The exhibit allowed a few of us to actually heft the armor and especially the sword. The old movies made it seem as if swinging broadswords was easy. It wasn't. The sword I lifted had to weigh, Easily, 35 pounds. If it wasn't, it sure didn't feel like it. I don't know what that is in kilos but that damn thing was heavy and I was used to doing heavy lifting on my job. I'll never forget the smirk on the face of the usher that guided us through the exhibit. That's when I learned that movies are Just fantasies.
That makes it at approximately 16kg.
To give an idea, a standard airplane checked luggage is expected to weight maximum 23kg (aside extra allowance etc., which can bring it to the "maximum maximum" of 32kg), so that means basically trying to swing around as weapon a medium weight piece of checked in luggage.
Plus, the armour problem we already mentioned. They had somehow lost the idea/approach of the lorica in terms of "effectiveness per weight and mobility", so, those things where thick, heavy (weight) metal (no high resistance lighweight modern alloys) with limited mobility.
I had the experience of wearing a full firefighter suit with respirator in a 30º C (86º F) June day, so I get the idea they were like cooking thin cans :-D (and I am sure theirs was much worst than mine, because mine was not a metal armour, and would probably allow a bit easier movement).
But ehi, I am not expecting a(n erotic) game to be fully realistic, and can enjoy a movie as entertainment, and I liked a lot e.g. "Excalibur", despite some people complaining about the depiction of armours there.
What makes me a bit more critical, is that it seems lots of people take Hollywood movies, whether set in ancient history, modern history or e.g. action moview, like if they were a faithful unbiased representation of historical events and of how things works in reality (including e.g. physics, IT), and that sometime Hollywood itself likes to leverage that with indications like "based on real events" (and then you discover that the only real thing is that e.g. someone stole something and everythings else is invented).
