You can lift it, great, fantastic. Now block as that 6'7 Scottish/viking/mongol warrior swings his sword at you.

Hilariously enough, you can actually put this to the test with decently realistic physics in the game Examina.

It's animations are based on procedural physical movements, and the weapon handling is based on the weapon mass, while the strikes and damage are based on the height/weight of the character + mass/design of the weapon.

You probably already know where I'm going with this, but that game completely changed how I view medieval combat. It's like a realistic version of HEMA. That is to say, I made a large, hulking warrior typically using a bardiche or flail. There are also women in the game.

100% of the time I just steamroll the women, joustle them and knock them over and while they're getting up simply crush their skull. Given that actual physics affect the weapons and character balance, the results when you pit the men against the women almost always has the same results unless the women are using polearms and effectively zone their attacker. It's hilariously brutal when you use a warhammer and one-hit crush their skull through their shield because the females don't have the strength to block an attack from a behemoth of a man.
