This is without question the worst video game I have EVER played, and I have played a lot of video games. It's just appalling. There are enormous stretches of the game where there is absolutely no requirement for the player to do anything, the combat is intensely repetitive, the writing is awful and the plot is non-existent. There is just nothing fun or compelling or interesting about it. The only emotional response I have to offer in response to it is sheer anger that I squandered any of my life playing it (and be warned: it is a VERY, VERY long game, so that boredom won't go away if you take the foolish step of sticking it out).
Please don't buy this game. Publishers can't push stuff like this and expect us to swallow it. Final Fantasy hasn't evolved in years. Play the old games, if you must, but in the name of all that is good in this world just keep your money in your pocket.
