"I have in fact made the decision to leave Naughty Dog," Richmond told IGN. "I love the company and the people and know that they will continue to create awesome games going forward. On a happier note, after careful consideration and exploration I have joined Riot Games. There is some really innovative stuff going on here that I can't wait to be a part of."
Previously, Richmond oversaw Uncharted 2: Among Thieves' multiplayer and worked as game director on Uncharted 3: Drake's Deception. He had been with Naughty Dog since 2008.
UPDATE: SCEA says "the development timeline of Uncharted will not be impacted."
