Not much to add in relation to game content. The dev wrote a post about his writing process. His goal is for readers to be immersed in the game as if they really were having a conversation with Steph. I made some comments about how immersion can enhance the game experience. To quote what I said specifically about Steph, "after having Steph as the antagonist for most of the game, its hard to see her as a trustworthy wife, that will take some work even with the reveal." The dev hasn't responded yet.
Apart from that the discussion revolved around the writing process, best GPU for rendering, and we touched on the late game monogamous content. Nothing specific, just how it will be a challenge to pull it off. He is being unusually tight lipped about content.
