I play this game everyday on my train ride to and from work and have to say... it is everything you can ask for in an RPG. The story is a bit weak but the gameplay is classic and the job system works great. This game is definitely one of the finest FF's ever made. If you own a DS and appreciate RPG's, there is no reason why you should not own this game.
I would actually give it a 9.4 out of 10 cuz of the lacking story, but a very fun game especially on the go.
This game has it all. After PLaying Final Fantasy III on the DS I can easily say that it has some of the best graphics currently on the DS. It has a great storyline and the action is relentless. The game is also very hard but enjoyable. If your a fan of the Final Fantasy series or a fan of turn-based RPGs in general you will definitely love this game. Other wise your better off playing something else.
