One of the primary complaints from critics and the general public with regards to Kingdom Come: Deliverance is the game's bugs. Many players have had issues, from saves to quest progression, and the team are working on patching the issues out, but it's still soured the release to an extent. The executive producer at Warhorse Studios, Martin Klima, is all too aware of that, and wishes that Warhorse could have polished the game before release, if only they had time.
We've seen those technical problems ourselves and, while they're in the game, they're undermining the historical illusion.
This comes from the latest Weekly Torch, Warhorse Studios' dev diary-style blogpost. In response to a question about whether he sees Kingdom Come: Deliverance as a AAA game, he says that the game bridges indie and AAA to an extent, and that a AAA game deserves more polish.
