What I want to understand is why they make most quests unimaginative. Of course, there is lack of talent, but is not just that.
I don't think the lack of talent is the main issue, although there's that too. Seems to me, as evidenced by the cut content shenanigans and 6 gorillion release delays, that the biggest problem was dismal management pretty much from day 1. Seeing as how InXile are a bunch of SJWs and hipsters, they probably operate by the "everyone is important, everyone should have a voice!" mentality and were in dire need of a brutal CEO-type of person to slap the shit out of everyone, get them to focus and cut out the unnecessary stuff that bogs the game down as well as assign more work to the actual talent in the company instead of the novice writers they've hired.
Right now, the game feels like the classic "too many cooks spoil the soup" syndrome, which is something that would've easily been done away by a proper manager.
