Wow, Blue Dragon is a masterpiece, don't trust the bad reviews at all!
Graphics: The graphics are really great. Better than most games that popped after this one. For an exemple, Lost Odyssey have better graphics in some way. But in general, the graphics of blue dragon have more vibrant colors, less aliasing, and looks way better because of the simplicity of the characters. If you liked the graphics of Dragon Quest 8, you will be impressed with this game. The only downside is that the game has framerate drops when, for exemple, you do some techniques. Wich is not bad but still, you can see it.
Sound: Master Nobuo Uematsu is by far the best soundtrack maker again. This game have a really superb soundtrack with the exception of the boss battles, which is a really not cool sound, lol. Still, you get used to it and right now I like it! :D It's just not the sound you would expect at all, especially since it's voiced!!
Story: The story is childish, and it is the only downside of the game for me, since I'm 23. A lot of Poo ennemies (poo serpent, etc.) and you can "search the poo" left by monsters to find items in it... well. Also, the story of the 1st half of the game is mainly for kids. But it ranks up during the game. The story is getting by far better and better, and at the 3rd disc, I can say I really love my crew. The character have a personnality, and background story.
Gameplay: The difficulty start really TOO easy, then the difficulty rank up. Not as much as Dragon Quest 8 for exemple (which I finished at level 34, that was hard, lol), but sometimes boss battles get really hard. Also, you can play on the hard difficulty if you want. But I'm pretty sure you'll have to battles all ennemies on your quest if you want to beat the bosses, or you'll have to be well organised. In general, you have shadows and they learn skills depending on their class. You can set them as monk, white mage, black mage, support mage, thief, etc. You get the drift. But this can be changed anytime. The abilities you learned can be used even when you set another class. For exemple, you can be a white mage that have the ability "black magic lvl x" and an ability that let you have the same defense you tank class have, wich is cool. The combats are REALLY fast and really fun. And installed on the HDD, the game load fast, and the battles load REALLY fast.
Finally: The game is now 20$, by all means BUY IT! It's better then any other JRPG I've played on the x360 but tales of vesperia. Better than lost odyssey for me (I LOVED dragon quest 8 and this game ressemble it a LOT)!!! If you loved dragon quest 8, BUY!, if you loved FF4-5, BUY, if you love JRPGs, BUY.
... What, you're still reading this? Go buy the game, it's worth 59$ so for 19$ or 9-14$ used, it's a miracle! :D
