Just a few of mine
Music that does not match the vibe. So I make videos and while some do not like it (I really do not care), I put music in as a background to give a better sense of the sexual vibe...romantic, rachet, sneaky, etc. With the right music you can literally have zero moans dialogue and other items for people to still understand what is happening. Music can easily change the intent of any sexual scene and some games do not pay attention to this.
This idea of "Dwarfs" Basically people calling the MC a Dwarf when they know good and well it is some little kid. These games just need to be banned and burned. I am sorry but while games are fake people using them to live out there pedo fantasies is not my cup of tea.
No animations. Like really, in 2023 people still making games with zero animations? I see this more and more with people using AI to make games. Very annoying. There needs to be a new tag called AI generated because it is all over the place.
Finally Fetish for the sake of Fetish. This is another I now make money trap that I see game makers, image makers, videos, you name it fall into all the time. FUTA and Incest basically are the most lucrative subject areas if your making a game, video, comic, etc..I find folks who never touched that area, suddenly started going down that path when they moved into a Patreon environment to the point that it is over done.
Which brings me straight to....
The rinse and repeat syndrome. I find this happens when folks start making money on their platform of choice. In order to keep the dollars following there is no time to think about plots, and what should happen next. Animations become stale, or modified versions of previous one, dialogue becomes basically unreadable, and models start to all look alike and content just becomes "meh" overall.
Crazy ass anatomy. I get it if you want your model (s) to have a 10-12 inch dick and Double DD tits. Fine. However when I start seeing Size HH tits everywhere and 20 inch dicks the size of a baseball bat (Doberman talking about you man), I mean shit.
