I bought Project Zomboid way back in the day, probably 9 years ago at this point, and one thing the devs do there is try to release a weekly dev log about what's going on, even mentioning difficulties. M&B2: Bannerlord's devs did the same, but bi-weekly, however in both cases the game was in development for exceedingly long time periods, so the devblogs were sort of there to tell people 'Hey, we're still alive!" - so if the UA:D devs made a devblog they could get away with one every 3-4 weeks or so too.
