If it's a rape game it's a rape game. But part of what makes futa hot typically is that they are so intrinsically hot that most people become into them near immediately, especially once they learn how massive and perfect their cocks are.
It's just less hot to even show this much work being necessary, even if it weren't so hamfisted. You could still contrast normal actually effective futa charm with mindcontrol without all this chicanery.
Yeah, no, that is not what makes futa hot, that is what makes futa hot to *YOU*. People are different. While I do like my futas with really big cocks, the trope of women falling right away for futas just because how big their cocks are is beyond silly to me and not the least hot (sure, one size queen LI reacting like that in a game/story, but most women are not that size obsessed).
In fact, I would like to see more futa games/stories deal with the fact that the large majority of women are straight and slapping a cock on another woman won't make them immediatly attracted to the other woman. Rape, blackmail and other non consentual means for the futa to get access to straight womens pussies is perfectly fine and hot to me* and way preferable to a futa that gets every straight women to fall for her simply by flashing her dick.
Also, for me personally, mind control has never done much. Morally, it is just as repulsive as ordinary rape, but as a fantasy it sucks for me because it more or less makes the other person into an object/a machine that has no real/own reactions and I don't understand the appeal of that.
But all of this is of course my subjective opinions and no objective truth and other people will think differently. However. This game is described by the dev as "dark" and the player will choose between a dom path and a sub path (in which there is also NTR). And we already have tags like corruption, drugs, domination, graphic violence, harem, humiliation, neotare, mind control and sexual harrasment. That kind of tells you what kind of game we are dealing with, no?
* The cononundrum of how to seduce/corrupt straight women can be combined with the futa being particularly horny (getting the horny impulses from both her pussy and her cock, from both male and female hormones), resulting in employment of unsavory methods in order to achieve immedieate release and satisfaction is a hot way to deal with it in my eyes.
