Blackmail is not specifically mentioned in Patreons TOS
police cant prosecute for fiction, well at least not yet.
Teachers Pet is made with Ren'Py and names can be changed easily in it or by using a script. With my project, I changed mother/son to stepmother/stepson and so forth. in hopes that I can get away with it on patreon will see they may have a problem with that as well. For me, the lack of Taboo just takes away from the story and let's face it is the taboo that makes us want to play the game in the first place even though we would never consider it in real life.
Big Brother is made with Unity I don't know how hard it is to change it's probably just as easy but I can say that I wouldn't like the game if it was changed.
Regardless of how hard it was, it can't be as hard as remaking a whole new game. No... there's a reason why DarkSilver went that route. He didn't like making Big Brother anymore. He went ahead and said so in Patreon. Giving up on the game is on him regardless of what Patreon did. That's on his track record. Tens of thousands of dollars in the drain. That's his prerogative but there should be consequences to his decision.
I don't doubt he can make good games. I doubt his discipline. I personally don't think he should be trusted to make complete games anymore. He can prove my statement wrong by making Glamour until the end but I don't see the likelihood of that since he's already making foolhardy compromises in an attempt to please everyone.
