Matt Bilbey, VP and GM of Football at EA Sports, explained a new live service called Football Club. It aims to keep track of all your progress across every FIFA title you own, and let you access your achievements and details on mobile phone and website. At no extra charge.
The idea is to keep your progress under one identity, but thankfully it doesn't sound anything like the subscription service that Activision recently announced for Call of Duty. Apparently EA Sports has more information on this service soon, so that might change.
