Jonathan LeCraft discovered his love of persistent multi-player games in 1991 when a friend introduced him to the text-based world of MUDs. He played and created in the ASCII universe until he was introduced to Ultima Online, a game that consumed his attention and eventually became his first job in the industry as a game designer. In his five years at Origin, he shipped several expansion packs for UO, working primarily as a system designer, and eventually lead designer. He then moved on to Blizzard Entertainment to work on a World of Warcraft as a game designer, now a senior game designer, helping to ship four expansions.
