like I said, and you even quoted: "but I'll admit a lot of it comes from there being several different non-overlapping incest genres, like for me the loli, shota, f/d are all instantly off, as is ntr ones."My man, we're talking about whether incest is underrepresented. Just because it may have overlapping genres that you don't like doesn't mean that those games don't exist. They're still incest games.
still the fact remains: there's very few games for people who look for the basic mom/son incest house genre. it's not like in 2018 when you got a few new ones every week, now it's more like 5 a year out of which 4 dies instantly. ask anyone who play these ones, they'll all say the same thing. (unless they love ntr, then there's more games).
it's kinda like how there's a million games with the tag 'lesbian' but almost none of them targets lesbian audience. or even hetero audience who don't want dick in their lesbians.
