Totally agree with the basis of what you said.What exactly is the main story though? I've said it before, but to me the main story is what the players make of it. You can cut out most Dylan/Ellie content at will, be a good wife, go for mostly the adult lesbian or hetero routes...and so on. There's a reason we get choices resulting in different outcomes. Some of which result in zero incest, others in more or less hetero/lesbian content...and so on. If you don't want to see any sexual content with particular characters in your game, you don't have to.
And I've also said this before, but that's pretty much the point of a choice based visual novel. You get to make your own story. Problem here is that most routes will only see content worth playing in 30-40 years from now, which might make certain other routes seem to be the so called "main story" as there's simply more content, which is caused by the game's development moving in slow-motion.
I personally don't give a flying fuck about the incest content in this game. I also don't care about children and teenagers. I'm in it for content involving adult characters (mostly hetero oriented). Thing is, I'm shit out of luck to get any of that within the next 20+ years probably. lol
If you don't want to see a particular fetish/route, don't play it.
This forum gets boring reading repetitive posts about people hating this or that fetish, when they have an opportunity to not see it!
If they don't like it and are watching it, why?!...or if not, why complain about something you're not going to see?!
I used to read every post on this forum, but I'm here now, mainly for the art.
