Put simply, there’s a lot more to account for during a fight in Kingdom Come.
There’s of course the complete absence of anything magical in Kingdom Come, which seeks to deliver a world based more in history than fantasy, but combat is also quite different. Kingdom Come: Deliverance has frequently drawn comparisons to Elder Scrolls games like Skyrim, and while that’s apt to some degree–they are expansive, open-world games that present you with a great deal of freedom–there are other areas where they greatly differ.
