I honestly think the whole "linear" argument is just bogus. Just about every single Final Fantasy has been this way. Even if it provided a big world map you really only had 1 destination you could go to anyways. I am about 11 hours into the game and have been able to fully utilize the battle system to it's fullest for quite some time now. The game has it's fair share of hard battles. To already be saying this after only a hour of playing really isn't fair at all. Give the game a full chance, i promise you wont regret it.
