Gregg Mayles, the director of Sea of Thieves and designer on Donkey Kong Country, has announced that he's left Rare. News of Mayles' exit was first reported in July 2025 during a rash of layoffs and game cancellations across Xbox Games Studios, but the short poem he shared on X today makes it official.With a 36-year tenure at the studio, Mayles saw its transition from an exclusive Nintendo partner to a Microsoft subsidiary. He helped design games like Battletoads, created Banjo-Kazooie and when studio founders Tim and Chris Stamper left in 2007, stepped up and became Rare's creative director. Mayles also led the team behind Sea of Thieves, one of Rare's modern successes.
