Are we still doing this? Relationship changer is the real incest and the story is irrelevant to whether the Marcus is the mc's father or not. There's no change in the story one way or the other and no indication that it's going to change. And there i no indication that the mom's husband is going to be anything more than a passing reference acknowledging they exist. Incest being off by default is kind of irrelevant since that's the case with every game on this site where the dev uses patreon. Even on games where it's batantly obvious what the true relationships are.
He's acknowledging that, but basically saying it's not canon since you have to edit the letter. And that the non incest version is the "true version" just because it's the default.
If it doesn't matter in the end, why are you all so upset?
The topic has been talked to death in this thread for years. Any further discussion should be held with forums admins. But I doubt that they will change the forum definition because of something like that. What there is to say about this has been said here, more than once.
In any case, I don't really care about the relationships. This is the same pointless discussion in other threats, "is it real cuckold or not? or "is it real NTR or not?" There are only extreme opinions left, real discussions and exchanges of knowledge no longer take place. And the people who shout the loudest, usually certain haters, are usually the people who have the least idea what they're talking about. It's unbearable to have to see again and again that some people just can't stand not getting their way. Things are sometimes worse here than in many schoolyards. I actually thought this was an adult forum?
I like this game exactly as it is. I don't care which tags are there and which aren't. If I like a game, I follow it for a long time, sometimes permanently, and make up my own mind. I only read the tags superficially. I have had the experience more than once that they are only partially true. And so the topic is now settled for me.
