There's actually quite a few people I've chatted with (in addition to myself) who rarely play AVNs more than 1-2 times, so on this point I agree that there's plenty of people that don't like to do multiple replays. For instance, I can count on one hand AVNs I've done more than 2 playthroughs, and probably less than two hands AVNs I've done more than 1 full playthrough (though I'm excluding ones where I get partially through on a blind playthrough, realize I've messed up badly, and restarted fresh for the rest of the AVN).
Yes, you can just skip through it to see alternate scenes, but that pretty much fully breaks my immersion as a reader. I almost never really enjoy the experience if I'm not fully rereading the whole thing, and I frankly only extremely rarely find an AVN that is interesting enough and that I have enough time to want to do that.
That said, I don't expect devs to cater to my reading style. It
is however why I generally favor games with only 1-3 LIs, that have poly/harem paths (particularly if they have a lot of LIs), and/or that don't force you to go exclusive until quite close to the end of the game. If I see an AVN with like 6+ main LIs and read that it starts branching to exclusive monogamous-only routes early, unless there's a lot of other stuff that hooks my attention (like a very compelling story), I'm fairly likely to pass over it in favor of other AVNs simply because I won't feel like I'm missing as much content by only doing 1-2 playthroughs.
Consequently, it should come as little surprise that the Jaye/Mal poly path is how I went here, and at present the only full playthrough I have (have a Jaye-only one also which was my first blind playthrough, but it's only at like Chapter 7).
I legit am interested in seeing the Mal+Amanda path, but as I mentioned before... I'll have to likely wait until I feel like a full reread of CS because otherwise other AVNs I haven't yet read are generally just more appealing to me.
