i really dont see how it would be that hard to, MOST of the main characters, have been remade in kingdom hearts 1/2 and ff dissidia or the other ff spin offs, hell even the movies, so they would already have good rendered 3D drawings/videos to go off of, and they already have the main storyline, so building off of that would be flying cake for the most part. Honestly i like the semi turn based action, thats why i love replaying 7 and 9 and (going to be soon 6), its alot of fun for me personally, having real time stuff isn't always fun, especially when you have to go off screen and shit to get monsters to re appear.
im indifferent mostly, if they made it, hell yes i would probably buy it and like it (hopefully they wouldn't change too much) , but if they dont make it, no big deal really, they are still spittin out other good stuff that i like so im fine with it.
i really dont see why people are getting up in arms about it, raging over this really doesn't seem logical... but whatever floats your boat i suppose.
