The claim gives the wrong release date for Sands of Dune. Macmillan's book page for the title lists its on-sale/publication date as 06/28/2022. That directly contradicts the article's date of July 28, 2022.

Because the publisher's catalog page is the primary source for a book's publication date, this is strong evidence that the article's date is incorrect.

The year attached to "Dune: Wedding Silk" is incorrect.

The official Dune Novels chronology lists the short story in its publication history as "Wedding Silk" (2011). A library/catalog record for Tales of Dune also notes that the collection was published in 2011 and includes the then-new story "Wedding Silk". Those sources contradict the article's claim that the story dates to 2008.

So the correct publication year for "Dune: Wedding Silk" is 2011, not 2008.

Abrams' official product page gives the full title of the first volume as "DUNE: The Graphic Novel, Book 1: Dune" and lists its publication date as November 24, 2020. That means the article's name "Dune: The Comic Novel, Book 1" is not the published title.

This is not just a style difference: the publisher's catalog uses Graphic Novel, not Comic Novel, and includes ": Dune" in the title.

The numeric claim is too low.

In this same section, the article lists the earlier released titles Dune (1992), Dune II (1992), Dune 2000 (1998), Emperor: Battle for Dune (2001), and Frank Herbert's Dune (2001) — that's already five games before the newer releases discussed below. Official sources then confirm two more licensed Dune video games were released later:

• Dune: Spice Wars — Steam lists its release date as Sep 14, 2023.
• Dune: Awakening — Funcom's official launch post says the game launched June 10, 2025.

That means there have been at least seven released licensed Dune video games, not six.
