KC:D doesn't have nearly the same insane potential as Kenshi, but the trade-off is that there's significantly more story to enjoy. It does so in an open world with multiple ways to approach any situation.
You start off as a peasant-nobody and have to build up your gear and reputation in a very (very) deadly world. The combat is deep and tactical, with dozens of different weapon choices from swords to maces. Clothing also plays a key role not only for defense but for social standing. And there's a crafting element that's rooted in real-life alchemy.
Kingdom Come is also significantly more polished and graphically pleasing than Kenshi, and looks utterly gorgeous on the PlayStation 4 and Xbox One, not to mention a high-end PC.
