They are so amazing at making system sellers that the Wii U sold poorly.
I’ll admit that Nintendo are first class at making games, literally second to none.
However their hardware department could do with realising it’s 2019. Also their system software department needs to learn how to implement an online infrastructure.
I realise that the Switch is selling in droves, but so did the Wii for the first few years, then the sales fell of a cliff.
