Although Sony is clamping down on saucy content in PlayStation games, Nintendo appears to be quite happy to leave any censorship decisions to rating systems.
The Japanese company recently reaffirmed this during its 79th Shareholders meeting, when president Shuntaro Furukawa was reminded about "other platforms" applying restrictions independently of CERO (Japan's rating organisation). This was his response on behalf of Nintendo:
Nintendo, as do 3rd-parties and their software, applies for an objective rating from 3rd-party organizations prior to release. If platform-holding companies choose arbitrarily, the diversity and fairness in game software would be significantly inhibited. We provide parental controls that can be used to apply limits.
glad to hear this. while there are questionable content that passes through the cracks of rating boards, i strongly believe that it shouldn't be the job of 1st party platform holders and any regulation and censorship should come from the rating boards.
