Kingdom Come: Deliverance and its sequel are games that pride themselves on their historical realism, with a story rooted in 15th century Bohemia wartime, characters based on real-world history, and architecture that closely resembles the buildings that actually stood, and in some cases still do stand, in that region of the world. But if we're talking about the first game specifically, there's one key aspect of the story that developer Warhorse well and truly whiffed, and that's how much in-game time transpired over the course of the main story.
During the epilogue of the first Kingdom Come: Deliverance, Hans Capon asks Henry how long they've known each other, having met near the beginning of the game, when Henry arrives in Skalitz as a refugee. Capon suggests it's only been a couple of weeks since they met, implying the entire main story took place over a matter of some 14 days, meaning in that space of time Henry went from being an orphaned son of a blacksmith with no combat experience to a master swordsman with a body count to rival Nathan Drake's, earning him the trust of nobles to carry out high-stakes missions.
