I really wish there was more content or a better emphasis on body types in the game. They could use the in-game fetish/preference system to have situations like "your player character loves being fat" or "this NPC is attracted to muscles." At the moment, I feel like there isn't any point in making a hot tall Amazonian, thick BBW, or twinktastic boy beyond purposefully opening up the descriptor for your own character. Lemme squish some belly fat, get sandwiched between buff meaty thighs, get complimented on my figure, that sorta thing.
I also find it somewhat odd that NPCs can spawn with fetishes/preferences that completely contradict each other. I had an NPC spawn with a fetish for raping others, but hated acting dominantly, which was confusing to deal with. Some of them make sense/have more in-game support (like being both sadistic and masochistic) but there's a possibility for a character to have a fetish for their own lactation but hate having their breasts played with, which means that trying to satisfy one thing tends to be at odds with the other.
Somehow my biggest gripe is having (female) 'taur NPCs be given the "dominant" fetish but their default positioning for sex is still "doggy-style." I get why, but I've seen great art & h-manga where the centaur-woman is fucking a guy in a vague "cowgirl" positioning, and I just wish it was more popular.
(Wish games just had suggestion boxes to let devs know more directly, dammit)
