Many people here think every adult game's a porn game and should follow porn logic. Most games on this site probably are, but there are a few ones that are styled adult games but not porn games. These are often targeted with whining by the forever horny crowd, who often find the idea there could be something like a non-porn adult game pretentious.
Yeah those guys aren't high in empathy.
It's probably true that it doesn't make the most commercial sense to reject porn logic, but most devs don't bring in loads of money anyway. Not everything has to be a money making effort, and it's sad if you think it has to be.
Most of what you write assumes that you are talking about a
porn game, so a game where porn's the core purpose. Later you mention adult games, but I don't know if you assume all adult games are porn games. But you sure don't eliminate that impression.
There's any number of reasons it'd be a good idea, those reasons usually involve plot and narrative. You know, like, the stuff
porn games absolutely suck at
and most other adult games aren't doing too great either. Maybe she's an antagonist and a normal relation wouldn't make sense and it doesn't fit the MC's character to rape her. Maybe she's a relative and it isn't an incest game. Maybe she's already someone's partner and it isn't a netori game.
Well that'd happen anyway, if she's like fuckable or unfuckable.
Coomers gonna coom.
