Maiya: They need to have that error code as a catch all so that it shows a "friendly" error message and not a huge list of code references where the error occurred. They have to have that because it is impossible to know what errors can occur, no matter how much planning and testing they go through. The word choice was probably to mitigate any concerns to the players if there was an error that was beyond normal. On a sad more personal note, their developers are probably going to die 10 years younger then they should after the launch of this game due to so much stress!
