Amazon Games studio head Mike Frazzini is stepping down from his role to focus on family, according to a report from Bloomberg. Frazzini has helped lead Amazon’s game division since 2009 and played a role in building the company’s game studio.

“Mike was there at the beginning of Amazon Games, and his leadership and perseverance helped build the games business from the ground up,” Amazon spokesperson Ryan Jones said in a statement to Bloomberg. “Our recent successes with New World and Lost Ark are the result of the long-term, customer-focused vision for games he helped establish. We are very grateful for all his contributions, and wish Mike the very best.”
