This game is fantastic and i daresay revolutionary, square have really gone all out in order to achieve a gaming experience unlike any other.
The intuitive design of the gameplay leaves me speechless, these are some of the more notable features i've come across that have just left me dazed in awe and wonder:

Disconnecting during boss battles. Isn't it great that when the tension is getting to its peak and we've been playing a good few hours and our hands are starting to hurt from manipulating the gamepad/mouse/keyboard, square have had the insight to make sure we take a break to alleviate the stress on our bodies and minds! Good job!

Disconnecting without loss of internet connection, server worlds going down or for any other discernable reason.
^ What I really like about this one is we're free to go browse the web and do literally anything else online when it happens! Clearly square care about us not losing everything altogether and all at once. Good job!
