it could, but it would be difficult, certainly not in a M&B. If weaps are to be made realistic, really realistic, then they'd need to add character balance, stamina, and poise. Some games tried and most fail at it, still if not overdone, totally do-able, though armor would be top priority, not weapons. (I mean, as Meta, it would reflect "reality", it's better to have an armor + spear, swords are basically garbage unless you are extremely skilled with them, and also armored). If a video game manages to merge M&B combat with KCD adding those kicks (poise, balance + stamina) it would make for a excellent video game imo, definitely the best medieval combat possible. Though huge battles would be either extremely rare, or non-existent too. Mostly skirmishes
