Isn't that 90% of the people on here though? I'm sure if you had to prove you were over 21 to post on F95, most of the prolific posters would disappear!
As an aside, aren't VNs meant to be escapist? I expect there are a few people who would like a "real life" VN, but I expect they are the same people who love a good grind fest in a VN too.
I think Nyx has done a great job making a complex story line into an engaging VN that happens to have adult content in it too. Is it going to cater to everyone's specific fantasies or requirements? Nope.
There's literally thousands of VNs on here - if you don't like this one, go find another. That's not to say you can't comment on it though; just don't expect it to change!
