I'm playing Bravely Default now and I love it...but are you ok with grinding a bit for levels? You have to level the jobs you want to use with each character separately. Then you can level jobs with each character to use extra support abilities or like a subjob with all the spells and abilities you have unlocked. So it's a lot of grinding to level the jobs you want and experimenting with the options.
For example I have a ninja which I am leveling but first I leveled up spell fencer in order to use the elemental enchantments for my weapons to exploit enemy weaknesses. Then I leveled ranger to get the accuracy and damage bonuses. So I had to level spell fencer to the proper level, level ranger to the proper level, then switch to ninja and level it but I can use every ability spell fencer has up to whatever level I leveled to and add the two support abilities from ranger that I wanted. So if you level a black mage to level 14 (max level for jobs) then switch to white mage, you can use all the black mage spells on that job too if you wanted. You can level multiple jobs and pick various support abilities to add to your main job. So a knight can have abilities from monk, swordmaster, and dark knight if you wanted. Each support ability takes up a certain number of slots, which is limited. You start off with one slot and eventually get up to 5.
Anyway my point is this. When you fight enemies you get experience points and job points. Experience points increase your level and stats (str, int, mnd etc). Job points increase your job level and at each level you get certain abilities and bonuses unique to that job. Job points don't come as quickly as experience so when you are building your character the way you want you need to grind a bit to level the jobs.
The good thing is when you do New Game+ you keep all your levels and gear.
Other games worth a look are Legend of Zelda Link Between Worlds, Fire Emblem Awakening(tactical RPG), Shin Megami Tensei IV(RPG), Luigi's Mansion Dark Moon, Mario and Luigi: Dream Team(rpg), Kingdom Hearts, You may like Super Mario 3D Land, I like Animal Crossing New Leaf, Retro City Rampage DX, Monster Hunter 3 Ultimate, Etrian Odyssey IV: Legends of the Titan(RPG). Some of these show off the 3D effect quite well which cannot be shown on the 2DS obviously but the games are still good.
