The story, to me, seemed in depth but the game play was too linear and the best thing about earlier FF tactics (i.e. Side quests) were totally removed from the game.
After a while it becomes a little tedious as you need to travel around randomly from map node to map node to gain the level required to the next part of the story where-after you must do the same thing all over again.
Its very easy to have characters die at the beginning of the game and since no suitable tutorial on how to keep characters alive is given Id guess most players would be turned off by this.
Also, once you actually learn how skill learning works, it actually becomes more fun as you try to max out your parties strengths.
I have rated it as a 4, but a low 4, like... a 7/10. This is because it only about does the job of entertaining you through those commutes to work, drives with parents etc.
The enjoyment of the game is definately based on the learning curb of it and to be honest, by the time you actually get around to learn the game the train ride is over and you kind of cant wait for your next chance to play it again.
Not for all gamers, but definitely not the worst game out there. I still play it even now after about 3 months after purchase.
