Players are *incredibly* hard to second-guess. With as many possible situations as players can come up with, testing them is extremely expensive, and I suspect their publishers didn't allocate enough funds to do so.
Indeed, with that many possibilities, the *first* thing you'd want to do to polish the game would be to do a massive test of the beta version with hundreds or thousands of players to expose as many bugs as possible. Which, critically, the Kickstarter gives them. That's new. I'd expect the beta to be buggy as previous Obsidian projects, but I'd also say that they have *much* more capability to improve on the beta than they have in the past.
I've gone from games programming to programming business software, and the latter has been *significantly* easier to bugfix in because the range of possibilities is *so much smaller* and in many cases *entirely deterministic*. In short: Players are pains in the arse. The games industry would be so much easier if we can eliminate them from the equation!
