Over the past decade, millions of players have filled out their character sheets following the rules designed by Jeremy Crawford, one of the most influential figures in Dungeons & Dragons.

A game designer and game master at Critical Role, Crawford has played a pivotal role in the evolution of the world’s most famous role-playing game. For years, he led the development of the Player’s Handbook, both in its 2014 edition and in the completely revised edition published in 2024, becoming one of the key figures responsible for defining how millions of people play today.

His work has also been instrumental in other key books of the fifth edition, such as the Dungeon Master’s Guide, Tasha’s Cauldron of Everything, and the 2025 edition of the Monster Manual, in addition to his contributions to numerous supplements and campaigns that have expanded the Dungeons & Dragons universe.

Before joining the D&D team, Crawford had already established a solid track record as a designer, having co-created the role-playing game *Blue Rose* and contributed to titles such as *Mutants & Masterminds* and *Warhammer Fantasy Roleplay*.

In addition to designing rules, he is also one of the game masters for Acquisitions Incorporated, the popular ongoing campaign that has helped introduce tabletop role-playing to new generations of players through live streams and international events.

His ability to combine depth in design with an accessible and flexible gameplay philosophy has made Jeremy Crawford one of the most respected voices in the role-playing game industry.

At San Diego Comic-Con Málaga 2026, you’ll have the chance to meet one of the designers who has had the greatest influence on the recent history of Dungeons & Dragons and discover firsthand how the rules that bring countless tabletop adventures to life are created.
