I'm seeing a lot of buzz over Nintendo's "Creator Program" (and don't worry, this thread isn't intended for the Nintendo section!), and thought I'd chime in on it to see if this will help clarify it for people in general.
There's not as much grey area as people are pretending there is. I've been considering making an entire video over this matter, particularly calling out PewDiePie for deciding against supporting Nintendo games (seriously, how arrogant is THAT?!). It tells me he's not much of a gamer if his priority in choosing to play a game is based on how they handle their ad revenue...
ANYWAY, let's use an example everyone can relate to: movies. Who here thinks it's okay to go to a movie, record the movie, and then upload it to YouTube and make money off of it? I'm pretty sure no one here would think that's okay. Videogames are not so different: recording gameplay and then posting it and making money off of it is a ridiculously self-entitled expectation.
To make the problem a little more clear: Sony and MS willingly spend WAY more money by monetarily incentivizing the licensing and sanctioning the use of footage (with obvious stipulations and limitations) as a way of marketing through end users. Again, this is SANCTIONED, meaning the license has been OBTAINED by a partner to use footage of said game. Nintendo's program here is DOING THE SAME THING: you have to put in your videos either via text or verbally the following -
"I have a license to use Nintendo’s content in this video through the Nintendo Creators Program. This video is not sponsored or endorsed by Nintendo, but any advertising revenue from this video will be shared with Nintendo."
This program is a COST-EFFECTIVE method of basically handing out licenses for end-users to utilize their content without having to go through the PROFESSIONAL channels to obtain a license like you would through Sony or MS (and obviously various other publishers).
In other words, this is all normal practices (albeit Nintendo approaching it rather differently), and people need to understand how content copyrights work before they start mouthing off at Nintendo. The millions of people getting away with Let's Plays of straight gameplay footage are flying under the radar and are essentially lucky they haven't been caught. I think that's mostly because of how hard it is to police millions of people on the internet, though YouTube is clearly trying.
Hope this helps!
