Leaving my 2 cents as a resident lurker.
Bear with me for the pointless preamble, KoD was a game i supported a few times in early development, and intended to keep throwing some subs every now and then (as i tend to donate to patreon projects by single sub rather than continuous, since i like many projects and don't have disposable income to support everyone).
Before anything else, this post reflects and opinion and is influenced by my personal perception, I want to say i like the creator despite the being a bit disappointed at how the situation turned out and am still hopeful that things will improve.
With that out of the way, i wish to politely disagree with some points being made.
Not every update was disappointing, I for one could accept updates early on as a normal thing since they were starting out, supposedly getting the hang of things on a new engine and laying out groundwork for more and faster content "in the future".
If i had to roughly point out when things started bothering me, i'd say maybe one or two releases before sierra left the project.
After that we had another round of getting used to engines and more assets, and after all that an extra delay.
Also, mentioning a lot of people keep paying for their patreon isn't a great argument when things like malise and the machine kept getting a large number of subscriptions while having nothing to show for it, you can study economy and or sociology to somewhat understand some phenomena that leads to this kind of situation.
A patron asking for results for their investment in an artist isn't unreasonable. Especially when said artist had produced expectations of more and faster content and keeps taking longer and longer for the same/less content.
Hence if patrons are not content it is withing their right to withdraw support until the creator shows that they are actually producing something and actually how patronage as a system is supposed to work (better than the original terms, as kings didn't take kindly to being lead around, tho I would discourage us from returning to barbaric methods even if we could).
That said, I have no idea how big this update is and as such it's a bit too early to draw a conclusion.
For now I am withholding my support (as meager as it is) until my doubts of hreinn are dispelled.
I am somewhat hopeful that this was just a bump in the road as KoD was a notch up in quality to the majority of projects out there.
