It's not a hard choice for me. If I want a quick fap, there's no shortage of talented SFM artists making animations these days. But they can't cater to more cerebral fetishes that require character development, like corruption. That's where games can excel, especially ones that allow you to tailor the experience to your own preferences. Those are rare, KP might be the only one with this level of interactivity while also having good art. Genre classics like Witch Trainer are much more linear.
Agreed, though I still would not consider KP 'cerebral' in its approach. Spoofy, intelligent (without being brainy) and witty - yes; but its approach to corruption is just too over the top and reliant on well-worn tropes to be taken seriously. Those defeated bosses who turn out to be either big, goofy softies (Tonkin), frail dirty old men (Scientist) or insecure alphabet males (Great Lizardman), all these absurd comments about sexual predation, the edicts that are unambiguous about their lewd intent (sexual performance drugs, anatomically correct model for lectures about female bodies specifically, security doors that may be left wide open, etc.) - it's just constant eye-winking... or is it really an eye that's winking?
As regards tailoring experience to one's own preferences, I've yet to see an open-world, sandboxy game that does everything right and does not take years of the player's real life to complete. I don't think there is such a well-versed pervert, who would be able to convey each and every aspect of human sexual experience to each and every viewer/reader/player's satisfaction. I read '120 days of Sodom' which is probably the bravest literary attempt at cataloguing sexual perversities, but with all its detailed, gory descriptions, Sade lacked psychological insight into the nature of human lust, other than abuse of power. The last hundred pages are hard to stomach and read like medical reports from murder scenes. There is this text-based game here on this forum, whose author took the enormous task of pleasing every degenerate and degenerate-in-denial and I criticised it recently quite heavily for meandering and adding little bits of everything that overall don't seem to do anything plot-wise. And earlier, I also had some questions about execution of different experiences in the game. You can choose physical gender and identity and orientation of your PC, but do they really play differently as different genders or is it just a purely cosmetic change of genitalia and pronouns, especially when it comes to sex battles? Because playing as a straight boy, you may end up having your dick raped by a girl's anus and thus lose your penile virginity. Is that really a thing?
Thus I'd much more enjoy a well-written sissification game and a well-written hardcore men-fuck-woman-till-she-swims-in-cum game and a well-written Femdom game and a well-written fem-slave game and a well written gay game than a jack of all trades that tries too hard to suck too many dicks at once, if you excuse the metaphor.
