I get the basics such as Vaan wanting to take back from Archadia what was Dalmasca's and other stuff but the politics are confusing me, the old English, and the voices don't help either.

1. How do you enable Gambits? I never figured it out. Because I got a new one for Baltheir but I can't turn it on.

2. What made them want to see Marquis anyway?

Geez, things were sure easier to follow back in the days of FFVII, VIII, and IX.
