It's quite simple actually. When you say futadom, people know exactly what you mean. There's no ambiguity there. When you say femdom, it can be a plethora of things. Including non-sexual stuff, which it unfortunately more often than not is with the way people keep equating foot fetishes to femdom. Something you yourself are doing. So the futas can fuck, get blowjobs and bust nuts all around, but the normal women only get their boots licked? Or pretty much only do things that don't involve them being pleasured? Yeah, no. Just call it futadom, we know where your biases are.And therein lies one of many nearly metaphysical tag/genre discussions, one that is tied to even trickier and more esoteric gender debates. Is pegging done by a sexless android (with an obvious femine form) femdom or not? Is worshipping Iris' boots, or getting whipped by her not femdom only because she is also a futa? You wouldn't even know she was a futa. Are various kinds of BDSM play (where you won't even see the cock), not femdom? Especially since most of my models have "hyper-feminine" thicc shapes and curves.
I can generate a lot of questions like that related to the game. You might answer that if X is done by a futa, it is naturally a futadom. That is true. But it immediately leads us to the sinking sands of a discussion about whether futa should be considered women. I don't want to engage in such a debate; I don't think it leads anywhere, and I think that both femdom and futadom are niche enough to not alienate people who enjoy both.
When I get back from vacation, I will be reworking the game's presentation here. Also to accent its nearly exclusive futadom nature, so that people know what to expect better. But until the tag rework is released, I won't be removing all mentions of femdom either.
