When it comes to being crazy restrictive on all things IP coupled with being amazingly combative with making lots of properties readily available for legitimate purchase, Nintendo barely needs an introduction. This is the company that has taken down ROM sites for classic games all over the internet, taken down fan-made games that use Nintendo properties, taken down all manner of fan-made ports of Nintendo properties onto other hardware, and has even taken down fan-made creations that involve putting Nintendo characters and the like into 3rd party creative games and software. Now, to be clear, Nintendo can do all of this. The open question has always been why it bothers to do so. What threat is a fan-game to legitimate Nintendo titles? Especially when Nintendo often times makes it quite difficult to legitimately get classic Nintendo games on its current hardware.

Case in point, Nintendo recently announced a new Metroid side-scroller that has Metroid fans very, very excited. So excited that some of them want to go back and play the classic Metroid games before playing the new title, only to find out that on the Nintendo Switch you just can't.
