The German ratings board USK has made an interesting statement regarding IARC. What is IARC? It stands for International Age Rating Coalition and allows developers to publish their games more easily. The developer will fill in a form and the IARC will calculate the appropriate rating for each region. Here is a video that explains it a bit more in detail.
Why is this important to Nintendo gamers you might ask? According to the USK, the regular digital store fronts will apparently join IARC at some point in the future. This includes the Nintendo eShop. You can find the full statement here below. Much thanks to Gerjet for the translation!
"The USK announced that they will, as a founding member of the IARC, handle the age rating for apps and online games together with their partners. IARC is a groundbreaking swift of turning regional rating processes in a globalized one for apps. As the first distribution platforms Google Play Store and the Firefox Marketplace joined the system. Other partners like the Microsoft Xbox Live Store, Nintendo eShop and Playstation Network are awaited to join in the future.''
