I just finished it. Boy, the whole game turns into an interactive movie that lasts from the moment you enter the monastery and until the end. You still have some chance to do open world stuff, but there is little point to, since at that time in the game you are swimming in cash, and the main quest is also trying to instill a feeling of urgency.
The interactive movie would not have been that bad, if the script was good and the acting/face and body animations were making the best use of the limited possibilities of the tech, a la Witcher 3. Alas, the acting is wooden, and the script is B-Movie grade.
The pacing and the Epilogue loredump was the cherry on the top. While it was interesting, for me personally, to learn the history and the motivations of the main actors, I was really already hurrying to finish the game by the time I got to the Epilogue. But the whole feeling of "let's just get this over with" took over me once I got frustrated with the monastery. Really that was the turning point.
As was already mentioned, there is no combat, skill, or economic balance to speak of in this game. However, it's tons of fun until you get too rich and powerful, and I will always use it as an example of a game that may be unbalanced but it's fun.
I noticed they have severely cut down on reactivity towards the end too - Henry almost got a choice in which way he will take part in the attack on Talmberg, but in the end he made a predetermined choice. Neither of the two guys you could surrender to the Bailiff in Rattay had any reactivity attached, though both seemed to hint there will be reactivity. Apparently there were plans for something there, but it was cut.
I admire the originality and boldness, and hope the majority of the bugs will be fixed, preformance improved, and new content will be better, move the story forward from the cliffhanger. I am not disappointed in how the story ended, although this is probably because I already knew that it won't be completely resolved by the end of the game.
Overall, I'd rate high and recommend to people, despite all the downers. This is a game you play for the story and role-playing, not for the gameplay loop itself. KCD relies much on the player to make it fun for himself, as opposed to make it into a grindfest. This means it has its own audience of players who will be able to appreciate it. The rest will keep ranting about balance and exploits, but they are missing the point and what the game is good at.
