If I understood, so instead of just making the patch to make the game nsfw, they will just release a fan mod that just add alternative scenes that are not needed just to have the adult stuff, if that's really what I'm getting, I'm not sure I want the game anymore, if the only way to get nsfw is on alternative story and not on main, so it's kinda just non-canon. Personally I will just ask for a refund and just buy the game if there's an actual patch, I only wanted the game when they said there would be nsfw stuff, and I really don't think I want it added like that.
