Big day-one updates have become relatively commonplace over the past few years, but it's still notable to see one come in at the size of some games. To play medieval role-playing game Kingdom Come: Deliverance, you'll have to download a colossal, 23GB day-one patch on PS4--but it includes a whole lot of performance, quest, and mechanics improvements.

Reports of the huge update surfaced recently on ResetEra, where players posted screenshots of their PS4 download screens with hours left before the patch finished downloading. To respond to complaints and frustration, Executive Producer Martin Kilma explained that developer Warhorse has made many improvements and additions since it had to submit a version of the game for certification. As a result, it needed a large first-day patch.
