So I have managed - at last - to listen to the interview of Alexander Mishulin on Owlcat Games stream recorded on December 10, 2021. I have found some interesting bits.
First, regarding the gunslinger and guns. I was wrong thinking that the class was too hard to implement for Owlcat. The reason is - Mishulin does not like guns in the crusade. He thinks that "the knights in shining armour" should not use firearms, that it is out of style. However, he said that in any game by the "Skulls and Shackles" AP the first class to implement would be a gunslinger.
Second, he considers the kingdom management an essential part of Kingmaker. In his own words, "Kingmaker stands on 3 pillars: Pathfinder role system, choices and consequences realized through branching dialogues, and the kingdom management." The kingdom management system went through 7 iterations before its final form, it was the part of the first prototype of the game ("the vertical slice" as he said). He did not talk about Wrath, but I'd dare to think that the Crusade mode was there from the start as well.
So if someone does not like the kingdom management in Kingmaker then you are playing a wrong game. Uninstall it and check what's up with Divinity: Original Sin 3.
Third, Alexander Mishulin graduated from the best Russian university - Moscow State University - as a programmer (though I suspect in his times it was called "applied mathematics"). However, he said that he was not very good at programming, because he did not like debugging. May be it could partially explain Owlcat's attitude to QA.
Fourth, general impression. Mr. Mishulin speaks in English slowly, but his language is very precise. He thinks on the words, but usually finds proper ones. On the contrary, his vis-a-vis who is a 25 yo community manager working on streams just spits out some words which maybe supposed to invoke some emotions, but bear little sense. I guess it might be a generational thing.
Fifth, Owlcat Games work like a proper corporation. During the interview there was a question in the chat about publishing the results of the survey. Mr. Mishulin said not a word about this. The community manager went on for 5 minutes explaining how those results are "boring", and how they want to publish everything, but "our young girls who are other community managers fell asleep reading the results and were able to go through them only because it was their job." Thus, they are sure that no one needs to see them.
I am sure that the core Owlcat audience - the ones who actually can achieve "Sadistic Game Design", for example - will be very glad to go through the numbers. I am also sure that Mr. Mishulin understands that - he is a very intelligent person. However, because all the interactions with gamers are in the hands of "community managers", our opinions are not read by people who actually understand the game, but by zoomers with no ability to process something more complex than a comic book.
In general, a very interesting and thought provoking interview. Even more interesting is that now it is removed from twitch and is not present on their YouTube channel. I have an audio record in an .mp3 file if anyone wants to hear for himself.
