Some more info about GRRM and Fromsoft collaboration-
-FromSoftware approached Martin for a meeting, but Miyazaki originally did not expect that Martin would be willing to meet him so easily.
"When we sat down together, it clicked right away. I proposed to make a game together, and he said yes. I was really surprised by how smoothly it all went."
-When they first met, Martin was already aware of Dark Souls.
-The collaboration started by Miyazaki explaining Elden Ring's main theme. With a mutual understanding of the game's concept, Miyazaki wrote the main story while Martin is responsible for the world's mythology. That means that in typical FromSoftware fashion, the player will be able to unravel Martin's backstory through fragments of environmental storytelling. Be sure to read all those item descriptions!
-Martin is not involved in the writing of Elden Ring's main story, because Miyazaki believes the format of video game could have limited the potential of his storytelling. According to Miyazaki, both the main story and Martin's lore are heavily influenced by each other
