It launched the 23rd actually. I would know, it was my birthday and you’re the one that brought up the 2019 dates in the kickstarter page. Which I explained.
Secondly this isn’t a beta, you’re playing the actual game. The beta was a few months in 2019 and we only tested gameplay segments, seeing nothing of the story until the early access launch in 2021.
As far as missing things, that would be the backer dlc, which shouldn’t be a focus til the main story is done anyway, and devotion missions, which we already know are in progress.
