Former World of Warcraft lead systems designer Greg "Ghostcrawler" Street has joined Riot Games, the company behind League of Legends. His new position is lead game designer, according to his LinkedIn profile.
Street quit Blizzard in November following five years as one of the most prominent public-facing figures on the World of Warcraft development team. As lead systems designer, he and his team were responsible for building and changing the fundamentals of the way World of Warcraft plays, including classes, game mechanics, items, trade skills and user interface.
Prior to his tenure at Blizzard, Street worked for just under a decade at Ensemble Studios, serving as a designer on numerous Age of Empires titles and as lead designer on Age of Empires 3.
According to his Facebook page, Street started at Riot in December. Polygon has contacted Riot Games for comment.
