Am I the only one that can't stand bad looking renders and badly designed and looking characters. I do value the story and narrative quality but if the game has bad renders and unattractive characters I lose a lot of enjoyment. For example I tried Sisterly lust but couldn't like the game due to the render quality and characters design. While game like become a rock star got me intrigued very quickly. I mean what's the point of not having the best possible looking characters in a porn game, why try to be too realistic, since it's a game. Say if the characters looked as good as resident evil remake games girls then it would be so good.
Your comment assumes a "one-size-fits-all" approach to beauty. That's not the way things are at all. I thought the girls in Sisterly Lust were very attractive and I enjoyed the game. It's a very popular game so there are a lot of other people who agreed.
You are correct in suggesting that people generally aren't going to play games if they think the girls are ugly, that's sort of a no-brainer. But everybody has a different opinion about which girls are ugly and which are attractive.
But then you suggest that every game should have "the best possible looking characters." This is bad advice that many devs follow and leads to many clone-looking, boring women. Sometimes an intriguing look isn't about being the best-looking. For example, in "The Guardian," there's a sexually aggressive, goth-style character named Lillith. She's one of the more popular characters on this site, but I wouldn't look at her and say that just based on the model she's one of the "best possible looking characters." It's her unique beauty combined with her style and personality that players love.
Furthermore, you seem to suggest that devs can just automatically create beautiful characters. Creating custom characters in Daz3d is a lot of work and getting the morphs and sliders to create an incredibly beautiful character is much easier said than done.
Finally, I would much rather play a game with mediocre girls and a great story than a boring, cookie-cutter story with stunning renders. I can't last more than ten minutes with a boring story. I could give you dozens of examples of beautifully rendered games that suck.
