Yeah, I get it; you have to draw a line somewhere with this sort of thing and unfortunately, not every idea can get included all the time. It's just kinda disappointing to think that such valuable content as the interactions between P and Storm is essentially exclusive to a romantic relationship between them.
I don't personally know how difficult it would be to rework this stuff to accommodate that choice - I imagine it can be quite difficult and time consuming, depending on how in-depth it went - but I do imagine it would be easier to implement that sort of thing now, while the Hinterlands are still something of a chief focus, than later on when there would be even more content to recode and whatnot. Not to mention that, as I imagine, most people will be either starting new saves or at least restarting from saves before Hinterlands III for the new content.
In the end, however, I'll trust the judgment of you guys that are actually making the game; if you think there's been too much focus on refining Hinterlands III and you just want to move on, you guys should go with what you think is best...
... That said, I can't imagine anyone would be upset with you guys for trading more time to provide more options for your players to explore the story in a way that's satisfying for them... I definitely wouldn't, at least...
But as I said, I'll defer to your judgement about this. I'm just one person who's suddenly voicing an arbitrary complaint; I understand that the wants of one person can't - and likely shouldn't - be allowed to completely shift your priorities or plans. In the end, all I want is see Minotaur Hotel become the best possible story that it can. All I can ever hope for is that my words be seen as the helpful and well-intentioned input I intended them to be; and if they have some positive impact on the trajectory of development, all the better.
Whatever you decide is the best course of action, I and every other fan of this project will still be here to experience this wonderful story you guys are creating! Keep up the great work you guys do with this project!
