Excellent story, definitly a refresher of the series.
First of all, Grandia III has an amazing storyline. It's characters have so much feeling into them because of the great voice acting. You really get involved and sometimes touched (that's right, I said touched) by the characters so much. It took weeks not to vision people I thought about as actual people, and not something that resembled a Grandia III character. The story is so deep that you'll dream of being a pilot and taking quest in these adventures yourself.
The graphics for this game are very smooth and flowing. It looks like so much time has gone into the little things, like the scenery. From the breathtakingly beautiful sunset over the mountains past the lake, to the blades of grass on the sides of your path, it's all a marvel to behold.
As for the music, the theme song for this game is very suitable. It's called "In The Sky" by Miz. It goes with this game because it's about a young pilot always trying to make their dream come true of flying and how good it feels to them. Which is much like the main character, Yuki.
This game is well worth however much money is being offered for it, and will definitly be "Greatest Hits" worthy.
