Not really. I do like some of my fetishes IRL too, but a lot of them are just fantasies. Incest for example is only desirable in games and videos for me.
Great graphics, at least an okay story line, somewhat believable scenarios (at least, believable in a porn-story), nicely written dialogues. That's about it.
Summertime Saga is such a classic, it was my first adult game, I think that's my #1, partly because of the nostalgy. I really liked Milfy City too though.
I think the success lies in the good ratios of great images + occasional animation. For example, 2-3 animated parts, plus a good amount of images from multiple angles is just such a great combo if done right.
Even if it will be THAT good, it would probably be regulated after they see the low amount of childbirths. If something has such a negative effect, the government can't just ignore it.
Never. If I'm not interested in the story and the dialogue, I'll just drop the game and find something else. If I wanted it only because of the porn, I'd just go and watch porn.
No such thing 😏 Seriously though, I don't think i can give a clear number. The creator has to find the sweet spot, where the number of characters doesn't make them boring and the story hard to follow, and at the same time, there is enough types of partners to satisfy (almost) every players'...
It can be fun, as long as it's now over-the-top grinding, with only occasional rewards for it. Some grinding does make the outcome feel more rewarding though, so I kinda like it.
