Namco's 10 grade.
The "Tales of Soul" allow you to find your own way (FF8 - Find Your Way) to finish it. At 2 or 3 battles you can decide witch way you'll get, fighting against extra fighters and add some of them too.
The "Chronicle of the Sword" is best them "Weapon Master" because to create your general and fight is better than use a original character to level up. Reaching the 20 th level with your created character's job you can by new jobs at the "Item Shop" and each "Chronicle Clean" you can get extra characters and new accessories to build players that you will use at "Soul Arena".
Each job have its own style, moves (some of them better than original players moves) and weapons never seen before. You can get the fighting style of the original players finishing the "Soul Arena".
I realy thought Tekken 5 was the best Namco's game, but after SC3 I surely changed my mind. SC3 is not only the Namco's best, is the best 3d fighting game. It's what I think.
