A significant faction of people like the idea that widely-played PC adventure classic Myst has recently gotten a remaster. A smaller faction of people within that significant faction does not like the new CGI sequences that were Full Motion Video in the original and the 2014 remake realmyst.
The new CGI isn't awful, and a lot of work probably went into it, but honestly it looks a bit like also-ran Civilization VI leaders doing Myst and doesn't quite gel with the realistic aesthetic that Myst leans on.
Naturally, modders have solved this problem(?) by doing what they do best. A nice modder has replaced those naughty CGI bits with upscaled versions of the original FMV. You can find that on the Steam forums. Because of changes to the game's plot, not every single CGI bit can be easily replaced by the FMV, and the videos won't sync 100% with what's being said. For all that, the developers of the new Myst have given the modding their tacit blessing, and that's neat.
