I agree with you here. For a slow burn VN, it is great to retain some interest, if there is a fear that no lewd content could be detrimential at the start (or even after the build up, if the story is written as such), or it can simply spark interest/conversation such as "this was great, but when will xy have such a scene?".I agree that the only useful purpose of a random hook up is very, very limited.
In a slow burn game it helps to make an early sex scene while we wait for emotional connection to the LIs.
So if I had a say I would vote for no rando shit when we are all eagerly awaiting the girls we have met and want so much (Stacy - secretly my sister)
But I do not recall this even going to a poll so yeah........
I think it is a very poor decision as well
Honestly this is really starting to feel like (pardon my french) that the MC is the dick, and the character is the attachment (or extra, or whatever you want to call him).
It could just be me, but this is how I started to percieve the story telling.
