P.S : I'm a submissive man IRL, I often fantasize sometimes as selling myself as a slave ...
P.S.2 : The true problem about your game is the art you've been using, even though you want to make your own world. It's too realistic, don't forget that people from EARTH are playing this game, not people from the world you make.
As a person from EARTH, I must STRONGLY disagree with pretty much everything you've said here. And you sound so naive. You fantasize about "being sold into slavery" without apparently knowing what slavery was like on EARTH -- the world we live in. Do you know slavery on EARTH implied things that are way, way, WAY worse than anything in this game? And I'm talking about EARTH here, not some digital world.
Look -- I get your point. This is too much for you. And that's OK: nobody has the obligation to agree with anyone else's kinks. But you have to be AWARE of the FACT (I'm overusing capitals to imitate your style) that there are many, many people who don't share your tastes. My kink is not your kink, and yours is not mine. Frankly, if anything, I think this game is too tame and soft -- I would like it if it were much more cruel than it is right now. Am I wrong? Is my mind "twisted" and "horrible" because of that? I don't know -- you tell me. What do YOU think when people who aren't submissive at all find out that you "fantasize about being sold into slavery"? Do you think they would say they "don't even know how your mind became so twisted"? Because I know a lot, a LOT of vanilla people in the real world who would.
You have to learn something from your own kinks, man, so you don't end up "not knowing what to think anymore." You are also a sick, twisted, perverted guy -- to vanilla people who don't understand what kink is about. Asking others how they can be "so twisted" is rather funny -- it's as if you just can't see yourself in the mirror.
Again -- it's OK if you don't like this stuff. The students are too young, so you can't appreciate it? FINE! You're entitled to that. Then: delete this game, and go look for something tamer, something that has people YOUR age as slaves so you can "fantasize about being sold into slavery" through them.
From my perspective, the things you complain about are exactly the ones that make this game good. And if this means you can't understand my mind -- just like vanilla guys can't understand yours -- then so be it. Go do something else somewhere else. This game is obviously not for you. And again, this is FINE. Not everything is for everybody. Hell, many people don't "fantasize about being sold into slavery," so I think even your fantasies aren't for everybody. Such is life, isn't it?
Well, go find something that makes you happy, and enjoy it.
Take care.
