Love Nintendo? Love it enough to dress up and cosplay, or create an original song that pays tribute to the House That Mario Built? Go to town, said nothing-but-class Nintendo President Satoru Iwata, in a shareholders meeting this week.

Just be sure to treat the IP with dignity, and you’ll be A-OK with Ninty Legal:

As the principle, please understand that the question is regarding a rather delicate issue to which no one can perhaps identify a clear-cut criterion. Of course, we cannot say that we can give tacit approval to any and all the activities which threaten our intellectual properties. But on the other hand, it would not be appropriate if we treated people who did something based on affection for Nintendo, as criminals. It is true that some expressions are detrimental enough to diminish the dignity of our intellectual properties, and others destroy our intellectual properties’ world-views by connecting them with something not based on fact. We think one of the criteria for deciding how to respond is whether the expression in question socially diminishes the dignity or value of our intellectual properties or not. Of course, it is very hard to have a blanket standard as this problem involves many complex elements that are very difficult to judge.

In these meanings, we cannot say OK to any and all such activities and, at the same time, it is not feasible for us to immediately respond to each small issue of this nature every time. However, these days an individual can easily transmit information through the Internet. Hearing your question today, as we cannot find these problems only by ourselves, we feel that a kind of contact window should be set up so that people can somehow report to us any inappropriate uses of Nintendo’s intellectual properties which diminish their dignities or values, so that we can respond appropriately.

Of course, it’s not a free-for-all, but this is nevertheless yet another reason—in a long list of reasons—to love the Big N. [Thanks, Kale]
