Nintendo issues copyright claims on Mario-themed Minecraft videos
Ars Technica 2016-05-20

The Minecraft community is one of the most video-centric gaming groups online, with hundreds of thousands of players routinely streaming and sharing gameplay and mods through YouTube and Twitch without issue. Nintendo, on the other hand, is one of the most restrictive game publishers when it comes to video, with a history of taking videos of its games offline and threatening to shut down livestreamed tournaments. It has also had problems sharing ad revenue with video creators.
When those two sides effectively merged through the recently released "Super Mario Mash-Up Pack" for the Wii U version of Minecraft, problems were bound to arise. And arisen they have, with a number of YouTubers publicly complaining about Nintendo making copyright claims on their Minecraft videos.
The issue appears to stem from the game's use of Super Mario 64 music, which is actually included as part of the Mash-Up Pack but still triggers a copyright match with the original Nintendo 64 game. One memorable video response from a Nintendo streamer urges the company to "stop trippin'" about the Minecraft videos. "It's like Nintendo doesn't want us to play their games. Don't play them because we don't want you to show them on YouTube. We don't want anyone else to see how great and wonderful the gameplay is..." the streamer says in his best mock Nintendo imitation.
