This reminds me of the trailer for Fallout 4. I was naive, expecting a repeat of New Vegas. Then I finally got to play it - while I found The environments interesting, the gameplay bored me. There were even parts of the game I didn't want to have anything to do with, such as interacting with Preston and base building.
My experiences with Bethesda games leads me to believe that they're satisfied to publish a game with less polish and more bugs than I find acceptable. I'll be keeping an eye on this, but I certainly won't be pre-purchasing or buying on release.
