Bravely Default is pretty cool, the story is standard RPG fare (In a nutshell, the four crystals that keep balance in the world of Luxendarc have been taken by darkness and this kinda set the world completly out of whack, you have to travel around Luxendarc awakening the crystals while fighting the Eternian duchy, which doesn't want the crystals to be awakened for some reason...), at least until several really spoilery things happen, the characters are pretty cool and memorable, the game also has Tales of style skits, called Party Chats.
In my opinion the strongest point of the game is the gameplay; it plays like the pre-ATB Final Fantasy with a key difference, in addition to HP and MP you also have BP (Brave Points) which are spent when a character takes an action (you start at 0 BP, acting takes it to -1 and 1 BP is restored at the beginning of your turn, so you end up with 0 BP again), you store BP by "Defaulting" (Which puts the character in a defensive stance and doesn't spend BP, so you would have 1 BP at the beginning of your turn. You can store up to 3 BP) and by "Braving" you can take multiple actions on the same turn (So if you had 0 BP you could brave once to act twice in the same turn and end up with -2 BP, you can brave up to 4 times as long as you don't go below -4 BP) If a characters BP is negative at the beginning of your turn that character won't be able to act. Bosses and some enemies also make use of this mechanic so boss battles are really entretaining and random encounters are much less of a hassle.
The game also has a job system (Like FFV or FFT) where your party members can have a main job (Skillset, passive skill, weapon affinities and stats), a sub job (Just skillset) and support skills, there are +20 jobs so you have a lot of customization options for your party members.
Fair warning, the game can get really grindy at times (Especially if you are like me and want to master all the jobs...).
Bottomline is, if you like old school RPG's you will probably like Bravely Default (there is a free demo on the eShop if you want to try before you buy).
