So I was choosing a new game, and I picked characters.
I had the Fighter listed, browsed right and got a Thief, then I browsed back and got a Black Belt.
Same thing when I had this Red Mage listed, I browsed left and got a White Mage, then I browsed back and got a Black Mage...?
What the hell?

Why is this?
What purpose does it serve?
Why can't you just browse through a set menu instead?
