@sebbysebbseb I wouldn't call it advertising the game since most of that ad revenue generated from those videos do not go back to Nintendo. It is also not out of the question that most people who watch an entire game campaign streamed on Twitch would have no reason to fork up the money themselves to buy those games since they've essentially seen [experienced] everything they need to see. Plenty of my friends have gone and watched Let's Play videos of The Last of Us and Grand Theft Auto V, finding no reason to buy those games anymore. On top of that, Twitch streamers instead gain those revenues, with some of the most popular ones like PewDiePie and GoldGloveTV making six figures a year streaming single player games for others to watch. Sure, they're entertaining, but that entertainment wouldn't exist without the video game to make commentary on, so shouldn't it be fair that some of that revenue goes to the developers? Maybe Nintendo's ad revenue ratio might be more than necessary, but they shouldn't be condemned for asking.
