First off , I have been getting the error since about 4:30 EDT, for more than 3 hours now! All this on a service that we pay for..... UNACCEPTABLE
Second, Not being able to sign in creates a WORLD of problems. You CAN play in OFFLINE MODE (If you unplug the Ethernet cord or disconnect wireless), with no saves (There in the cloud). This means if i want to play, I'm starting from the beginning. That is if the game will even load!
Titanfall. NO Playability
Spark, NO Playability
Plants V. Zombies. NO Playability
KI Loads With local playability
BF4 Single player only, no saves
COD Single player only, I did not check saves
All this on a system that DOES NOT require a internet connection.
