If sounds like you're saying you want this to be an adult game but that the adult stuff will come in at the end. Which means 80-90% of it is going to be story, romance and action. You already have fans who love your story and hopefully will support you till its concluded. But, don't you want to win over people on the fence?
Imagine someone trying this game after 0.06. They'll have to go through 2 hours of story and grind before they get to any adult content. I don't think its that unreasonable to want a balance between erotic scenes and story early on, if you've classified it as an adult game. It's usually a writing block where writers can't think past the first sexual encounter. They believe it breaks all sexual tension, which isn't true at all if written well. Even if you pick up a soft erotica title that's targeted at the female market (who supposedly prefer longer build-ups and romance), say an Anne Rice book, you've got more erotic content and build-up there in the first quarter than this game has.
Anyhow, it's good to hear the focus of 0.03 is on the love stuff.
