I think it does matter a lot, as far as development of game is concerned. Game is developed at Patreon, and they do ban incest.
Well, incest tag here hardly constitutes legal definition of incest.
Still doesn't really matter. F95 is not exactly patreon.
Sure, you're not entirely wrong: In my opinion this is also not what I would think of, hearing the word incest.
In my opinion, incest would mainly be fucking
your mother your '
landlady' or especially
your sister your
'childhood friend/female roomate'.
However, I posted you the rules, and that is how F95 interprets incest. Thus, this game got the incest tag.
Because this is the thread on F95 about this game. This is not Patreon.
Problem? Tell the admins.
Maybe Patreon got a different definition for incest than F95 does?
Maybe that's why TheGary decided that the game does not include
"Fuck your Mom and 2 Sisters (one's Asian the rest is not but ignore that) on a yacht, dominate them and beat the shit out of 'em by spanking" so he can keep up his Patreon?
Don't know, don't care.
However, you asked about the relationship between MC and the girls and about the incest tag.
Rachel is married to MC's uncle (his mother's brother, so relationship by blood). However Emily is not Mr. Elwell's child and Chloe is adopted anyway. Yes, it's no relationship by blood but by law.
I'll quote you the rule about tags again:
Incest [Sex act between family relatives, including those not related by blood.]
