I love that idea and I can understand what you're saying. It's a "you had to be there moment." Even if it's just a telling of the story that anyone can do afterwards, what is hard to replicate and impart is the matter that the initial storytelling occurred. The natural gathering of a group of people and whatever naturally lead to the story being told in the first place. The energy of the people around the campfire and their interactions with the storyteller who then in turn interacts with their words. It's just like Asterion remembering the good times he had talking the night away with guest. He can tell you about it and you can empathies with the way the memory clearly changes his mood and body language but the tale will not have the same magic as it did for him.
Though the more you talk about it, the more I really get intrigued from a creator working with a muse aspect and how online experiences like boards can inspire such a captivated piece of media. I think despite how much the internet is a big part of most of the world's lives, most would dismiss such experiences and interactions as pointless or a way to pass the time when it was absolutely necessary to the creation of something like Minotaur Hotel. To see you talk about it so passionately about those times and seeing you and the rest of the team put so much heart and soul into MH, it's inspiring in itself.
I'm sure as with most creators, you may look back on the writing itself and cringe a little; not because you're ashamed of what you created but because you've grown as a writer and it could be better with "rules of storytelling and writing" (though I'm sure given the limitations of the medium of an image board, it's likely the key source of the structure that could be better.) I would still be very interested in seeing a comparison of characters and plot points or maybe even reading it myself someday but yeah, I don't want spoilers. That's why my request was for future people once MH is completed. You also can't really do an accurate comparison if one half of the content being compared isn't complete.
Something else I should have originally commented in regards to the question of how much adult content would be in build 0.5, is that I appreciate not forcing any NSFW content in the build for the sake of having sex content in your adult visual novel. That's not to say I don't like seeing that content (I love me my sexual content) but I always appreciate when the sexual content is woven into a narrative naturally rather than being there for the sake of it. Like Luke's sex scene informs his character and doesn't seem force. The casual nudity with Kota is more of an adult mature thing rather than sexual. The build up to a relationship with Asterion feels like it would be more fulfilling than just banging him. I'm really enjoying more of the casual build up of potential sexual tension with Asterion such as the long looks and the lingering touches. I'm sure there'll be more of this and that's enough for me. We'll get to the banging when we get to it.
Though the quest being a raunchy version of the MH might make a good read someday (maybe we should distinguish the two by dubbing the imageboard quest as Minotaur Quest?) in a future where MH is complete. I'm sort of jokingly picturing Asterion having a conversation with the MC on a serious topic while the MC is riding Asterion. Did the quest have equally dark themes and tones in it like MH does? Or were the some of the more darker aspects just not as focused on?
