Funny how out of date people think Nintendo is. This is the one instance where Nintendo is ahead of the times.
It won't be long before all big companies start asking for their cut of things too. I'm surprised it has lasted this long with it being free. Companies are greedy at nature, its their job. They are there to make money.
Just like how DLC is now no longer a question but an expectation companies getting a cut of revenue will someday be the norm. People will blame Nintendo, just like people blame like EA or something for DLC, but it was going to happen sooner or later. I'm surprised and not surprised Nintendo was first. Surprised because Nintendo always seems last to adapt to things and would also expect companies liek EA or something to try this first. not surprised becuase Nintendo is the most anal and protective of their IP's out of any company I can think of.
But Pewdie pie and other youtubers/twitch/ect peopel should really plan ahead. To expect to not have a company who's game you are playing want a cut is a bit rediculous thinking about it. Hell Youtube takes what like 40% of their revenue, why would htey not expect the game they are playing and getting viewers due to to not want a cut as well.
