Dude, I've been paying for the game pass for 2 months. Enjoyed Forza throughly and i fell in love with.
First: As mentioned before, it is not what it people are making it look like. It is a matter of ecossystem. if you have a google account, you see the ease in loging in and creating accounts everywhere. This is a similar situation. I am not enforcing bias when I say Nintendo shouldn't have let this happen from a Business standpoint. Cross-Play is awesome, keeping stuff from games like Minecraft is too.
But if Nintendo allows this the way the unrespectable people in this thread are assuming, Nintendo itself WILL lose money in many fronts. If the case is a game pass presence in the Switch, as it has a lot of third party games, these same games wouldn't come to Switch.
Nintendo is letting another ecosystem in its own, and this has its ups and downs for the income. Nintendo regulates, sells dev kits, and also gets money from every step of a game to be released on its system, as any other company in the business. Letting Live be there the way some people are assuming IS idiocy at its best. They share a big market share with MS even though Big N thinks they do not. People would rather buy a game off live or game pass than going to their store for example. Anyway, from a user standpoint, this is a dream coming true and I agree with that, but as I said. MS never really cared to participate in this business to explore production of entertainment in the first place. They always wanted to win then living room with some gadget to bring Windows to it, as Bill used to say when xbox og was released. If there was something better than gaming, they would have opted for it instead.
They never cared how they would do, and this new approach is just a revamp of their old intention, changing the business model to confort their own, but nowadays they dont want only the living room, but being present everywhere. It is not to say this is more than business. Not saying it is machiavelic to want this. Just saying Nintendo, given all this info, should not have let this happen.
