Talking of RPGs, imo at its core a power-fantasy is nothing more than a regular RPG that puts the PC at the centre of its narrative while providing a multitude of paths and one optimal one, that you usually can go down by going the extra mile. So while functionally a power-fantasy because of the porn aspect, i still wouldn't call this game one because it often just lacks the most basic of choices (beyond sex stuff). And i think it does so because the writers' perspective just intrudes too often on their writing.
Like, from the writer's perspective the foxes weren't meant to come across as a bunch of soul-sucking assholes, so you can't talk back to them. Mallachites weren't meant to come across as a weird grooming cult, so they're the best people ever and here's your temple. Everyone practices slavery, but because reasons only the orcs are bad for doing it and just accept it. Gweyr the kidsslayer and Kiyoko the terrible mother are actually upstanding citizens, so god forbid you ever question them. The Champions needs to like Cait because she's actually lovely, the Champions needs to be Agni's whipping boy because she's actually just spunky, and so forth and so on.
It's honestly odd. Those themes and characters wouldn't even feel bad, in absense of choice, if they were treated with a measure of awareness, but it's all just so biased. Don't question anything and like what we like, kinda thing. Which is why i think Wsan is as appreciated as he is around here. He doesn't provide much choice either, and he doesn't write the most complex of characters/situations, but at least he doesn't impose controversial takes on the player/character.
