Well they went more action RPG style because they wanted to reach a broader public and thus dissapointing there fans that played I-X-2 but well thats the Enix part of it they rather make more cash or atleast try to and lose alot of loyal fans, i myself give them a deathline of final fantasy 15 if they are still screwing up a game that sold miljions of copies i'll just stop playing it all together. Hell I played FF 12 just half way in the game and just stopped playing, i finished 6,7,8,9 atleast 5 times each and still replay them every now and then.
But then again there are 0 to none other J style RPG's anymore, they should make a petition or something to bring it back becasue I DO NOT WANT to walk with my character if i do i'll go play mario... i want a normal ATB battle were i have attack-magic and so on so on and limit breaks and summons with cool CGI's that actully go away after you cast them... But just look at the PSP there are 0 J style RPG's same goes for XBOX360 and PS3 (as far as i know). Just because the engines are powerfull and you CAN make it more movealbe and shit like that it doesen't mean it makes it any better.. but that's just my opinion.
