As of this post’s writing, Hyrule Warriors: Age of Calamity is available to play in regions that include Australia, Japan, and all of Europe. Because of this, fans have begun to live stream it on Twitch and YouTube. Unfortunately, it has become clear that Nintendo really doesn’t want you to do that for the time being.
Multiple streamers are reporting via Twitter that their accounts have been banned for streaming Hyrule Warriors: Age of Calamity. Nintendo has been issuing claims citing “copyright infringement” and/or gameplay from an “unreleased video game”, and this is the reason behind the decision to ban the streamers. The bans are temporary ones that will last for 48 hours.
