There were a lot of cut corners with XCX when it came to enemies and NPCs. The pop-up on NPCs and some enemies was horrible, with them clipping and not reacting to the environment at all.
In BOTW, the enemies will hunt and cook food and react organically to how you fight them. They will use different weapons. They will run away if out-number. Actual fighting in BOTW is more complex too, with climbing and motion-aiming with specific hit points. Hit detection, clipping, physics, and AI are absolutely on a whole different level in BOTW.
I'm not knocking XCX, I loved it, but I can't pretend it holds a candle to some of the things BOTW does. The rock monster fight in BOTW is leagues beyond anything I've saw in XCX from a technical perspective, art-style notwithstanding.
