That's not the problem. To me, honestly, there are cases in where the game says the father died and you went to live with a friend and add incest tag. That's not the same thing to me, if the game intends for incest, it shouldn't make you imagine that it's really incest. Take for example Cure My Addiction, you're living with 2 girls that are adopted and looks absolutely nothing like your stepmother that was temporarily married to your father and the game has incest tags. Whereas, take Summertime Saga for example, the main character is described as living with a life long friend after his father died, you can tell the game is incest themed, because the characters look like the mother. If you like incest, at least in my opinion, it doesn't feel the same when you say, your mother and father died and you went to live with your mother's best friend (timestamps), it's not genuine.
