Playground Games Developing an "Open-World Action RPG"

After spending the last several years working on the well-received Forza Horizon racing series (not to be confused with the primary Forza series, developed by Turn 10 Studios), British video game developer Playground Games has told GamesIndustry.biz that they're now working on a highly ambitious open-world action RPG. I call it ambitious because they're putting 200 developers on the project and have been hiring key talent across the industry:
The newest addition to this project is Sean Eyestone, who takes on the role of production director and leaves his role as senior producer at Battlefront II developer EA DICE. Prior to this, he spent ten years working at Kojima Productions on various Metal Gear Solid games, including open-world entries Metal Gear Solid V: The Phantom Pain and Ground Zeroes.

Previous new hires for the second team include chief designer Will Kennedy and principal combat designer Juan Fernandez di Simon. Kennedy joined in July after eight years at Rockstar North, working as level and game designer then senior online mission and flow designer on Grand Theft Auto V.

The office will be home to more than 200 employees, who will all work on Playground's open-world action RPG. Combined with the established Playground studio, this will bring the company's headcount up to more than 400.

"We're delighted that we've secured a second studio to house our new team," CEO Gavin Raeburn tells GamesIndustry.biz. "This is a hugely exciting project that is already attracting world-class talent to Playground.

"The combination of new blood and experienced Playground team members is already showing huge promise and I'm excited to see this talented group contribute to Playground's continued success."
Given their relationship with Microsoft and the recent suggestion that the Fable franchise is ripe for a return, I think it's at least possible that this new game just might be a Fable title.
