Guess how long will it takes for complete the game, 10 yrs?
It's been 2 months but no actual contents update yet.
I bet the day won't come lol.
Most early access games update every 4/5 months with more content and smaller bugfixes in between the major ones.
With the first release they also made their development kit, usually this is the part that takes more time, once it is done things run smoother.
So, considering that the total of chapters is 30 (I might be wrong here, too lazy to check the kickstarter updates now) and that the first release contains 3 chapters, if we assume each content update will contain 3 chapters and will take 5 months to develop we are looking at a 45 months of development left, so, the full game game would release sometime Q4 2024.
If I remember correctly the kickstarter campaign started May 2019 and by that time they had a demo/concept build, so yeah, checks out, 5 year development cycle for a small team, it is pretty average, specially if you take in consideration this is their first game.
And please, don't take me wrong here, I would like to know their roadmap as much as the next guy, afterall I backed the kickstarter...
This is just an educated guess.
