Four of the top 10 neighbors are Video Game Franchises, yet the single strongest pull comes from a podcast — Critical Role at 0.85 — making D&D Beyond's audience shape broader and more cross-kind than a pure gaming profile would suggest.
Similarity here measures how closely two entities' audiences resemble each other in composition. Dungeons & Dragons leads at 0.92, the only neighbor to clear 0.90, and is itself classified as a Video Game Franchise rather than Toys and Games — the same subcategory as D&D Beyond. That means D&D Beyond's single closest neighbor is technically cross-subcategory. After Critical Role, the next tier clusters tightly: Diablo (0.79) and Wizarding World of Harry Potter (0.78) sit within two hundredths of each other, followed by Magic: The Gathering (0.77) — the only other Toys and Games entry in the top 10. The remaining five positions span a TV show (Challengemtv, 0.75), two more Video Game Franchises (World of Warcraft at 0.74, Dragon Age at 0.74), an Actor (Tom Felton, 0.73), and another Video Game Franchise (Sea of Thieves, 0.72).
Tallying the top 10 by subcategory: five are Video Game Franchises, one is Podcasts and Radio, one is Movie Franchises, one is Toys and Games, one is TV Shows, and one is Actors. The broad shape reflects an audience that overlaps substantially with fantasy and RPG gaming communities, a tabletop-adjacent podcast, and a movie franchise — with no single subcategory accounting for more than half the set.
The overall picture is an audience defined less by a single medium than by a shared genre sensibility — fantasy, role-playing, and speculative fiction — expressed across games, podcasts, film, and television.
