I dropped KCD 1 after ~30 hours for the same reason as you, but at least KCD has some justification - the whole point of the game is to be an ultra-realistic simulation of medieval life, a roleplaying game in the truest sense of the word.

Your character starts out not even knowing how to read, even though you, the player, obviously do to interact with the GUI. He’s the son of a blacksmith who never would have learned anything else, so he, the character, has to spend time learning basically everything, even if you, the player, already have it figured out.

You and I think that design is unfun. Clearly, though, there’s an audience for it, as KCD 2 sold something like a million copies on launch day and instantly recouped their development costs.

I thought that didn’t work?

Others have already pointed out important things about what the dev has said; I would like to add that the book the game is based on has a number of female characters which are simply not in the game.
