Re: Wolf's Dungeon
Anyone good enought to clarify that for me?
I am not a lawyer, and all that, but here's my take on it:
Take Yuna from FFX, for example. In the game, she's this innocent "Stay away from the summoner!" character,
and there's tons of character progression and build-up that slowly adds romantic tension as the story progresses.
Because of that, you have an easy starting point for porn, because you can take all that pre-built character, and resolve some of that tension,
like, say, showing what really happens when she's alone in that isolated room with the big powerful spirit...
But if the backstory didn't exist, you'd just be making mildly odd tentacle porn with a generic big-boobed heroine.
So in effect, you're profiting / gaining a competitive advantage from using someone else's work.
You're not directly de-valuing theirs (people are still going to play FFX after watching porn of it), but if you took their part away, your work wouldn't be worth as much.
Now, as far as I recall, many countries have variations on a "Fair Use" law, by which it's okay to parody or critique something without their permission. (Since otherwise, all negative critique would be illegal, which isn't ideal...)
And usually, if your work is sufficiently "transformative" it's also okay - an artist building a pony from ripped-up comic pages probably doesn't need to pay a license to the comic company.
That said, I think I remember someone arguing that Japan does NOT have a transformative clause in their fair use law.
In their system, any use of someone else's creative work is problematic, it's just usually ignored because huge companies don't have the time suing every table at comiket.
But that's why you'll often see dlsite imagesets that are obviously some popular character censoring parts of the name, or just never using it to begin with.
