I guess the new team has a hard time coming together and pick up from [when Sierra] left.
The prevailing thought is that Sierra and Nomo had creative differences, and Sierra was also busy with her own projects (plural!) and thus she left. Neither Hreinn Games nor Sierra will elaborate further on that front other than that they separated "amicably" on good terms.
Sierra is an excellent communicator as evidenced in her own projects and was pretty good at building up hype talking about
KoD despite its complexity and the team was doing a good job rolling out those early updates. They never recovered from losing Sierra as their PR asset.
The "new" team trying to gel together is an oft-quoted excuse since they were basically there since the beginning. Work started for the game in 2016 with Nomo and Sierra, and the first major release was in 2017. Monaco Dingo, a coder if memory serves, and Ndsferrari, the programmer, were part of the team in 2017. MD has since left and Monsinne, the writer, has been with Hreinn Games since 2018 at least but likely sooner when the other guys came on board. They've been using that tired (paraphrased) "the team is still coming together" excuse years after they've formed. This is fact. That grace period is long over.
Re: Nomo - Nomo is the artist, storyboarder, lore creator, and world-builder for the game. It's really his game -- his vision. Nomo went through a very rough time in the spring of 2020. Delays then, of course, were completely understandable. However, it's been over a year and the game has steadily been moving slower ever since. Well truthfully, the game was moving closer to its glacial pace even before then.
That's just the current state of things. The game's development is
slow, simply put. And from what we know, with no good reason since Hreinn Games really don't tell us why in an earnest and honest manner. We all hope for the best but fear the worst -- that they're taking advantage of their supporters. If only they communicated better, they
probably wouldn't appear quite as shady as some people believe them to be. But that's for each individual to decide if they are or not. I'm just laying down some facts in regards to the team. Alrighty guys, be safe, be kind, and stay awesome. Cheers!
