This tale is definately worth seeing if you have a Xbox 360 and are a fan of JRPGS.
There are cities in the world (Terka Lumeris), and each are protected by a "blastia". They basically ensure peace and order within the city. One day, a blastia is stolen in the hometown of Yuri Lowell (you play as him most of the game), and he goes after the thief. He meets characters such as a noble named Estelle, a hot-headed blastia researcher named Rita, among many others. Of course, that "chase" turns into a save-the-world kind of thing, involving bad guys who want to use the blastia to take over the world, the "empire", etc. The story lasts about 60 hours. There are also a great deal of side quests to do and daring achievements to unlock as well.
Those of you who are new to the series will find the anime graphics simply beautiful. That also means that Gears, Halo, and CoD4-ists may think that "It's not very detailed, so the graphics suck" when they're wrong. Everything from the character models, environments, and even the anime cutscenes have all gotten careful attention from the developers at Namco Bandai (or should I say Namco Tales Studio, Inc.).
As far as the gameplay goes, it's the same-old same-old town-dungeon-boss-repeat thing, with your inns, shops, bars, etc. at all the towns you visit. The battle system, however, is in real-time. (You still have the battle transition animation, though.) You can attack or use magic (called "Artes") at will, though some Artes require time to charge (mostly for Estelle and Rita). You can work up combos with button mashing, but later in the game, and for boss fights, you will also have to think about item use, etc. You can use items and change AI settings at anytime by calling a menu with the Y button.
Also, during most boss battles, there are "Secret Missions". This means that you can do certain things during a boss battle (attacking while it's down, destroying support objects, etc.) that earn you 5 GS each as well as other in-game rewards, provided you win the battle, of course. These missions can either be a walk in the park, or hard as hell, depending on the difficulty of the boss.
The sound is also of excellent quality. There are multiple battle themes, which plays depending on whether you're fighting a boss or not, what kind of boss, and what part of the story you're in. Some of the town music is also very good (espically the Dahngrest town music). The English VA is very decent as well. And in case you haven't heard, "Ring A Bell" from Bonnie Pink is the game's theme song.
All in all, this game is one of the best (and best-looking) RPGs for the 360 since Eternal Sonata. If you are a fan of the Tales series or RPGs in general – you HAVE to add this to your collection.
