Game of Thrones author George R.R. Martin might not have written much of Elden Ring, but that’s because it’s a FromSoftware title at the end of the day.
In an interview with The New Yorker, Elden Ring’s director Hidetaka Miyazaki explained how he worked with Martin. Apparently, Miyazaki put some key restrictions on Martin during the creative process. Not to hinder Martin’s freedom, but so that FromSoftware’s core design principles wouldn’t need to shift significantly with whatever Martin came up with.
