First, these are drawings, not actual people. There is no victim and any "age" is assigned, not inherent.
A drawing of a girl with small breasts and minimal curves can be "12" or she can be "18" depending on a whim. The inverse is also true. What we're talking about is pure fiction.
Now, that being said, there are always people looking to attack over any perceived impropriety. Because of that, I don't blame Nintendo. They have to protect themselves first and foremost.
The best way around this, usually, is to simply change the age. That doesn't always work, of course, and depends on the story itself, which should take priority. If you need the girl to be 13 in the story then she should stay 13. If not, change her age and leave the mature content in. I can't speak for this game, however, as I know nothing about it.
For all you know a pedo could use it as inspiration to act it out. I am willing to bet it has happened. They should not under ANY circumstances be placed in the sexual context
For all as you know Rambo was the reason someone grabbed a gun, and killed people. Let's ban those! It was Silvester Stalone's fault, no wait, the writers. They are the horrible murderers! Next up, you'll be saying GTA V was the reason shootings happen....oh, wait. That already freaking happens in the news. What do all those asses say what should get banned?
Respond to this picture. If you don't know what's going on, in this episode of the simpsons. You'd think this episode is teaching pedophila. It comes down to context. This is all fictional. And aimed at a certain age group. Should this episode of the simpsons be banned. Because a child could accidently see it and think sex with a child?
This is a bad example. A very bad example.
For starters, that looks either a midget or an doll. As a matter of fact, in this scene, she's a midget pretending to be a doll. No one is is going to be cross-eyed and in such a stiff position under any normal circumstance, and even in bizzare circumstances.
Also Moe Sizlack can be a lot of things. But people know he's not a pedophile.
"It comes down to context"... You're literally taking this picture out of context.
No because a child is not going to see an episode, where Moe Sizlack is panicking becuase he thinks his date is replaced with a doll, only for a second later the date to say she was pretending to be a doll, startle Moe, and still be panicked, and then pan to commericial. That's due to the fact that, in context, That's whats's going to happen in the span of about 5-15 seconds. The child will not just see one still frame of an animated episode with sound somehow not on and think that, and somehow, just somehow the child magically did, anyone reviewing the episode to verify whether it was the case or not... would not. Mainly due to the fact that in context, which again, you have taken this out of, no one would see a problem with Moe dating a midget. Except Moe, and that is within the context of her being a midget.
