It's a huge turn-off for those who are not into it. Ages ago I'd almost have sympathy for those requests. As there were barely any such games who focused on that fetish. Every porn site is flooded with futa/shemales. If you want to have futa, just make a game focused on that fetish instead.

I've made a set with this theme before. The animations are included in this collection.
As for Tourist Tap, this is planned to be a very expansive experience. If ever there will be such content in it, it will be entirely optional.

Dedicating a good portion of the development to a niche which disgusts most of the audience. Why does it have to be there? Why? Why not scat, guro, necrophilia, and or pedophilia? Make it entirely optional. It's completely "fine". I just wrote it, so it must be true /s.
Scat sounds nice and also some level of guro. In fact the new game I'm working on will have some golden showers as a feature (which might be optional as well considering the relative notoriety of this fetish). Having said these, there will be no pedophilia at any time. Zombies might be a gray area for necro. As for the futa options as a possibility, it will not involve the main character as he is hetero but futas or gay characters appearing as a part of the story or the game world are there.

the /s stands for sarcasm. I wrote it that way as to point out the absurdity. Just because you want something niche doesn't mean everyone else wants it too. Those who are into straight sex are probably not all into transexual sex. Although there are always exceptions to the rule.
