The dev was up front about that, as I recall, at least with respect to the AVNs with cameos in this one. 6 had more set-up than reveal, but just because Riley tells you nothing and Shelby's dad reveals nothing doesn't mean nothing was put in place. As an old guy, the presentation methods can be a little jarring to me, too, but that does not make them bad, it makes me old. Roll with the story as it is told, and enjoy.
My issue with 6 is that it didn't have much in the way of set-up and even less in reveal. 6 was just a series of porn scenes with not much else. It's akin to fan service. I was rolling with the story up until 6, but 6 had no story to enjoy. Episodes 1-5 were good. 6 was a step in the wrong direction.
