Tim Schafer is also "SJW" as fuck. There is many reasons he is super sexy other than his rugged good looks.
who gets to police the line between tastelessness and bad behavior? If the answer to that question is anyone other than NotMiki, Whose Opinion Is The One True Measure Of Objective Value, then you have a problem.
Well in this case it is a government appointed board and you deal with whatever they say because we don't actually have anything like a constitutional right to free speech. If the board says you can't sell it, you can't sell it and a whole bunch of the reasons that something can be rated the way they are (or refused classification) is based on that board's interpretation of what is socially acceptable.
Specifically from
hereRC (Refused Classification - Like Hotline Miami has been)
Computer games that:
(a) depict, express or otherwise deal with matters of sex, drug misuse or addiction, crime, cruelty, violence or revolting or abhorrent phenomena in such a way that they offend against the standards of morality, decency and propriety generally accepted by reasonable adults to the extent that they should not be classified; or
(b) describe or depict in a way that is likely to cause offence to a reasonable adult, a person who is, or appears to be, a child under 18 (whether the person is engaged in sexual activity or not); or
(c) promote, incite or instruct in matters of crime or violence
And when you drill down on to the specifics of what is acceptable in R18+
The content is high in impact
R 18+ material is restricted to adults. Such material may contain classifiable elements such as sex scenes and drug use that are high in impact. Some material classified R18+ may be offensive to sections of the adult community. A person may be asked for proof of their age before purchasing, hiring or viewing R18+ films and computer games at a retail store or cinema.
Also of note is the glossary definition of "reasonable adult"
Is possessing common sense and an open mind, and able to balance personal opinion with generally accepted community standards.
But, even when the broader community disagrees with the board you don't have a way of really defending it, because it is the board that determines what the community standards are. When you refuse classification the community is also hindered from making a judgement on its own, because they cannot legally acquire it.
Also note that there is still yet another rating over R18+ that is available for films but not games. For years the "community standard" dictated that Films could be that much more explicitly targeted towards adults rather than children. Even still an outright pornographic game is technically going to be illegal.
