I don't hate fat people. I just don't want to watch them while having sex.
About this last part I completely agree. If this game is for me - future will tell. For now it is. If it continues in same fashion than it will continue to be. If it goes in future with forced sexual content related to that or any other fat or old male than it will not be, and I'll delete it from hdd, unwatch thread and say goodbye. It would not be first time and I'm pretty sure it will not (if it happens) be last time. I'd be reluctant to see that happens, but my gosh, it is what it is.
For example, there are few games which I like but they had one or two scenes which I can't tolerate, and I'm not lazy, I dismantle it, remove unliked scene from game, rewrite few dialogues if needed, put it back together and continue to play homemade moded version.
As you mentioned incest, for example from that kink(which I also don't like, but i can tolerate) I can remove myself and not be happy but still be able to continue with gameplay. And few other kinks, but this one is not one of those. It's complete dealbreaker.
