George R.R. Martin Confirms Game Consultation

A blog post by George R.R. Martin reflects on Sunday's conclusion of the Game of Thrones television series. He discusses the ending of the show and what he's doing with all his free time, which thankfully includes continuing to work on the A Song of Ice and Fire series (along with producing no fewer than eight television series and development of feature films). He also drops an itsty-bitsy tidbit about video game work, saying: "I’ve consulted on a video game out of Japan." This jibes with a recent report that Martin was working with FromSoftware on an RPG project. This remains unconfirmed, but a post on Gematsu (thanks GameSpot) cites a "person familiar with ongoings at From Software" saying this is the game to which Martin is referring, a project they've been asked to refer to by its initials, G.R. Adding to the speculation, WCCFTECH has details from a post on 4Chan saying this title is to be Great Rune, a "true successor to the Dark Souls game," which will feature a Norse Mythology theme. If the rumors are correct, we'll learn more about this at E3. In the meantime, here's more of what Gematsu hears from their source:
A person familiar with ongoings at From Software has told Gematsu that the project—said to be known internally as “GR” (Gematsu has been asked to only share the acronym) and in development for the past three years—is an open-world title (with horse riding) and collaboration between Hidetaka Miyazaki and George R.R. Martin published by Bandai Namco, which will be officially announced at Microsoft’s E3 2019 press conference.
