Someone remaked Super Mario World in 3D in Unreal Engine 5 (no realistic graphics). The video explains what he did and its super interesting and entertaining to watch. However, there is nothing playable right now. And even if there was one, Nintendo would be fast to remove it. I hope he will publish a finished work as Open Source project, so it will live on forever.

Made in Unreal Engine 5.
Honestly if he tried to publish it as is with Nintendo assets, he’d get sued into oblivion. Hopefully, he either puts up the basic framework sans the assets or perhaps it gets “stolen by hackers and put up as a torrent.”
As long as he does not make any money and it is not about a current gen game, its not as bad as you might think. He does not directly use assets from Nintendo, as everything is self created. The only thing in the way is, that he is using the IP (Intellectual Property) and names. But you know what, there are thousands of fan made games like that - ton of them even using assets directly ripped off Nintendo games, and they are not sued. People do this kind of thing since decades.
Nintendo goes after the ones that get too much media attention. And the number of posts I’ve seen about this one suggest it’s making too much noise.
