While loved by fans, the Turn-Based Battle Systems are early FF´s most downside.
I have to argue over that every time with my girlfriend or other gaming friends.
"how can you play this... it´s just hit a button and wait what he does, you do nothing, there is no skill in this, blah blah"
What really pushed ME of the FF-Train, it was the "every-time-re-invention" of a turn based system, morphing slowly to action based gameplay in every release...
Final Fantasy 13 being the end of that Era, and being reached it´s very bottom at lightning returns, which would be better of with DMC Gameplay than this foul hybrid with some "turn-based" touch...
