A long-time Electronic Arts executive has left the publisher.

Frank Gibeau was the executive vice president of EA Mobile. Before that, he was the president of EA Games and EA Labels. As first reported by Polygon, he left the company he joined back in 1991 — a publisher he helped build into one of the biggest and most influential game companies in the world.

“It’s been a really great ride, the best job ever, jam-packed with incredible life experiences and filled with many great friends,” Gibeau told GamesBeat. “After an incredible 20-year career, I’ve accomplished all that I could have imagined and more. I’m very proud of all the great games that I had a chance to work on. I thank EA for the opportunity and wish them the very best. I am excited to explore my next challenge.”

“Throughout a more than 20-year career, Frank’s made many significant contributions to the company, our people and our games,” EA told GamesBeat. “Most recently, he’s worked to strengthen EA Mobile by building a great team. We thank Frank for his achievements at EA, and we wish him all the best in his next chapter.”

Before going to EA Mobile, Gibeau had helped the publisher develop some of its biggest franchises, like Battlefield, The Sims, and Madden. Gibeau had helped EA Mobile generate more than $500 million in revenue in 2014. We do not know who will take his place EA Mobile.

“We have strong leadership across EA Mobile today, and the team will report to me directly as we work through our long-term organizational plans,” EA chief executive officer Andrew Wilson said in a statement sent to Polygon. “I look forward to working closely with our teams throughout EA Mobile and continuing our momentum.”
