another thing i want to point out for the realism in Kingdom Come, I was tasked by some bandits to sneak into a place and kill someone. I did so, I then disposed of the corpse by floating it down a river.
I went back to the bandits and said "hey, I killed the guy" only for them to respond with "ok, cool. where's the body?" when I didn't have it they told me to fuck myself for not having proof. It was only because I still had his knife on me, which I used to kill him, which they recognized, that I was able to complete the quest how I wanted.
oh, another detail I forgot about Kingdom Come. The stamina system. If you run out of Stamina in a fight, I swear to fucking god, you start taking like 500% damage. You can shrug off blows no problem if you have plate and full stamina, but you tire yourself out and an enemy comes at you? you get SHREDDED. I remember running out of stamina and dying not 2 seconds after from FULL health because you just get dropped.
