As long as the inevitable "choice" that locks us in to a particular girl does not arrive until at least mid-game or preferably later (this is all I ask). It is the one thing that tends to annoy me about non-harem games: when the forced choice is presented too early. Sure you can cheat a time or two, but devs never allow that to go on for long before the discovery/punishment phase.
Also, once you are forced to stop diddling the other LIs, then what becomes of them as AVN characters if they are not allowed other relationship (I suppose they can all become nuns or lesbians...or both
but what is their connection with MC)? How boring will your interactions with them become? Are they just going to let you watch them slam clams from the cuck corner? Or will you only do fetch quests for them with no reward? "Thank you so much MC, you are nice person."
Maybe you get a glimpse of them during a peep scene, but other than that, they are might as well be background characters at that point. Since we are all stuck living together in a house for summer, it is not like you or the characters can go away when rejected. I guess you just nod politely at breakfast table and go on about your day.
Again, as long as the choice comes later in game then I do not have a problem with it.
