I don't really like fetish shaming, so I won't really ever insult someone for liking a harmless fetish. But The only "issue" I have, is when a great game like this could be ruined because of it(the problem with the law part). Part of me is glad though that patreon has that rule, because I got to enjoy that game so much more and so many others on this site.
I mean it's true that there are many games out there, but not a lot of them are done well or not already have baked unavoidable fetishes I don't enjoy like incest. I've tried to find games like this, but I couldn't. This was my first game on this site which had everything I could ask for, from avoidable ntr(which I like simply for the scenes, not as a story) to a love/corruption route with harem+netori element which I love. Not to mention that the "fucked up" story, is under the mc control rather then a sad spiral ending in losing everything you love(so far atleast).
So for me that rule allowed me to enjoy something I wouldn't be able to otherwise, and I'm glad the way saddog was able to write it the way that he did. But I can imagine the mental gymnastics an incest write has to go through if he doesn't want to end up with "landlady" route of the patch.
