terminally online people when they see a porn game that doesn't represent all and every single fetish, kink, role, gender, genital and identity on a mathematically perfect equilibrium
for a more serious answer: it's a porn game. It's not a political doccumentary. Of course you will notice only certain things represented, porn games will most often only show the kinks and preferences the creator enjoys.
what's next? you're going to complain to lesbian women if the smut they create doesn't have any heterosexual sex in it?
