This year’s Gen Con event is one Wizards of the Coast has said it’s “pulling out all the stops for”, with a keynote to be hosted by Theo Solomon (who played Wyll in Baldur’s Gate 3) including a bunch of announcements about what’s coming up for Dungeons & Dragons. One release seems to have been leaked early: a crossover with World of Warcraft.
According to a news post on virtual tabletop Roll20 that has since been removed (you can find it on RPG site EN World), we can expect Warcraft to get at least a setting book for D&D 5th edition, as a couple of Magic: The Gathering worlds have previously.
This wouldn’t be the first collaboration between Blizzard and D&D. Around the time of Diablo 2 there were several official books by Wizards of the Coast adapting the world of Sanctuary to D&D’s rules. Later there was a World of Warcraft RPG using D&D’s 3rd edition, though that was published under the terms of the Open Gaming Licence by White Wolf, the publisher responsible for Vampire: The Masquerade (which also has a D&D crossover in the works).
I can see why die-hard WoW fans might enjoy having a version of D&D with rules for playing a tauren or whatever, but Warcraft has always been so close to D&D I’m not sure I need a whole rulebook explaining its slightly different version of elves and whatnot. At least Diablo’s heavy metal vibes made for a different-feeling kind of fantasy, but Warcraft is as generic as they come.
