I feel like you have Nintendo confused with Square-Enix. As far as I know, Nintendo is one of the most chill companies out there when it comes to fan works. Heck, someone has almost finished an entire remake of Metroid 2 without so much as a whiff of legal action. (search for "Another Metroid 2 Remake" on your search engine of choice) Not to mention the mario dimensions (or whatever it was) fangame which was a complete hack of Super Mario World to span multiple worlds. (such as the Halo one) Or the Mario fangame which allowed real time editing of levels. (Mario X I think? the dev went on to make Terraria, if I remember correctly)
