To be perfectly frank its not just FF that has gone downhill, the whole rpg genre has. All the latest gen consoles have had barely a handfull of good RPGs and alot of rpg making companies decided to choose the cheaper option and develope for handhelds. RPGs take alot more development time than most shovelware/that next fps for what seems to be a less reliable customer base(Valkyria Chronicles anyone?). Why else have we not seen the next breath of fire?, suikoden, etc. Because RPGs are not where the money is at anymore and trying to make your game appeal to the majority and not its niche seems to be a safer bet perhaps.
