How historically accurate is Kingdom Come: Deliverance, really?Fiction

In-universe lore. Claims are judged against the fiction's own canon, not the real world.

Warhorse sold Kingdom Come: Deliverance as the most painstakingly accurate medieval RPG ever made - so it surprises players to learn its hero never existed, its opening massacre is pinned to a charter Sigismund actually signed on 23 March 1403, and the studio's own historian calls the whole thing 'not an open-air museum.'
