i think FF is all about story and adventure, a role playing games about ordinary dude that dragged to save the world from destruction or Armageddon, that is the essence of final fantasy that i played from 4 to 13, and the battle mechanic is always changing sure it always turn based strategy in its core even in 13, and its only change to action rpg in 15 (not counting MMO) so i gues everyone in fandom just try it the demo and read the review, and beside that SE can't please everyone else and someone, somewhere will find their beloved FF series, just like me with FF 6 and 7, despite everyone said it was overrated.
and for me, story is always number one, don't care about battle mechanic, so if the story is good, and the world of it is interesting then i don't give a damm about how i battle monster, but if gameplay is solid then it was plus.
