I can't imagine anyone paying attention to this game who doesn't like futa. Unless it's just an act of desperation because there is scarcity of content elsewhere, it would seem a terrible move.
Regardless, walking into Futa H.Q. and saying "Be less of the entire core of your being" isn't exactly fair. I'm sure people who like normal porn react quite negatively when futa is inserted into games they enjoy. And by "I'm sure" I mean I have seen this with my own eyes.
Moreover their vitriolic response is often coupled with some sort or moral justification, using words like "betrayal" or claiming the purity of the game has been tainted or infringed upon.
This isn't even to downplay that mindset. Much the opposite, I wholeheartedly agree. Games with a core fetish being inundated with antithetical content makes them worse, in some cases "broken", and should be avoided. Nothing about a well-made porn game should kill the boner of the core audience.
However, if we believe that rationale, then the argument becomes "Why are there any non-futa additions to Tits?" and that's actually a good question.
Most people come to Tits because they want to encounter space women with 20 inch penises and have them brutalize their holes. Why? Because that has been the core of all of Fenoxo's games since the beginning. It's what they are about, and what they best provide. The complaints here stand as testament to that fact.
It is only because they are well 'fed' that futa fans do not complain the same way saying "Why did you add a man with an 8 inch penis into my big dick futa game?"
But as we have seen, they would have every right to make this complaint. I'm guessing for a fair portion it'd be non-content.
