Why can't we have characters like in FF4 where they were just about all quite accomplished before the game even started? Or in FFT where they were still no-name squires, but still with a few years of training behind them at the outset.
The idea is that they have training before the game ever started.Also, try not to forget that any myth is greatly exaggerated... but even Tidus had his mentoring from Auron the master samurai. Just don't take the training at face value. Imagine the two have spent a considerable amount of time training. How f-ing boring would the game be if you were playing as a character described as a novice seriously. You'd spend the first forty-eight hours of the game training him to even reach his mentor's level. Then the rest the game wouldn't even seem appealing anymore because you'd wasted so much time doing nothing already.
