Grind grind grind.
Overall it was a great game... but I wouldn't know how great it would be compared to the other games in the Final Fantasy series. I really enjoyed the story.
I'm also not a big fan of turn-based RPG's, but for some reason FF3's system captivated me... maybe it was the graphics. I would say that the graphics are AMAZING for the DS.
The downfall of this game would be closer to the end... Basically you have to clear 5/6 bosses... WITHOUT ANY SAVEPOINTS. So basically before you even attempt to try the bosses... you have to GRIND. GRIND. and GRIND. some more..
