Can I install FIFA 14 on my phone, running Windows Phone version 8.1?
FIFA 14 requires a Windows Phone with 1GB of RAM to run, so unfortunately the Lumia 520 will not run this game.
If you search for FIFA 14 in the Store app, it won't show up as games or apps that require 1GB of RAM are hidden.
If you happen to open a direct link to the game, either on your phone or via the Windows Phone website, you should see a message saying...
Your phone doesn't meet the minimum requirements needed to run this app.
