The day FIFA 14 releases is the same day as the first patch comes out. Take a look at this post on the official EA Forums:
First, we want to thank everyone that provided feedback on the FIFA 14 Demo on Twitter, Facebook, and the EA Forums. We’ve been listening to the comments and our teams across the world have been working hard to prioritize and address the items that have been brought to our attention.
Upon starting up FIFA 14 for the first time you’ll notice a title update will be made available. The update addresses stability issues found in the closed beta and minor fixes to a couple game mode (Skill Games, Creation Centre) items. Please, if you haven’t done so already, be sure to restart and download the title update in an active session as this will enhance stability when matching up with other players online who have accepted the update.
Our commitment to improve FIFA 14 is on-going, and regular feedback from our fans helps us prioritize and identify future improvements. We wanted to take this opportunity to address a few more items that we continue to work towards. Firstly, we got some great feedback on gameplay during the demo and early access period, including:
• The effectiveness of headers from corner kicks and crosses.
• The effectiveness of finesse shots.
• The accuracy of lofted through-balls.
We look to update you in the near future with good news on the identified gameplay tweaks.
Finally, we’re aware that some users are experiencing freezes during the game. We continue to investigate these reports internally, and with our partners, and will update the community when we know more.
Thanks again for your continuous feedback on Twitter, Facebook, and the EA Forums.
