I've played the beta dozens of hours. I belive I was in the last chapter, but a major bug left me stuck, without being able to progress. So I took that opportunity to just stop there (my intention was just to play the first chapter, as I don't like to play too much of the EA releases, to keep it "fresh" for when the full version releases).
I've enjoyed it very much (I was afraid the dark, industrial theme/scenarios would be too monotonous and unattractive to me) and I'm 100% sure I will play it again when it's released (I should be done with Starfield and Cyberpunk by then).
Edit: I'm not surprised with the release date. The game was less buggy than the full relase of Kingmaker, for example. It still had some missing assets, the combat still needed a little more polish and, of course, the major bug I've mentioned above... But it didn't feel like it needed to be delayed for next year. I'm expecting a pretty stable release, just like WotR was released in better state than Kingmaker.
