I would definitely say that this game is for the RPG fans. If you were into the first Final Fantasys for example then you would probably like this game. It definitely is more up to date on turn based combat, really fun to play. Even if you just like good stories its worth giving a try.
Hmm...mostly, for fans of this genre (jrpg)...BUT..this game is a very enjoyable one, so even if you aren't the biggest fan of turn based battle, I would still say give it a shot! If you like games like Paper Mario and Pokemon, give it a try!
