Its not a high horse, maybe you should respect their craft more? No matter what, they are creating and telling stories, and although there's a lot of trash, there's some really amazing writing and world building in some of these games. Censorship is damaging regardless.
It doesn't matter what she looks like, the facts of the writing are what matters. There are plenty of porn actresses that look underage and in this case we're talking about animations, not even real people. It's not illegal, its just them forcing their own moral code. Video games and animation should have no more restrictions than literature.
Feel how you will, I don't really care, but you can fuck off with that high horse bullshit. Sorry I have a high opinion of creativity no matter the medium. And whoever said porn can't be art? Especially when sexuality and violence are two of the most allegorical themes.
