Someone

1. PAL has 9 additional enemies, the 8 dark aeons and Penance.

2. PAL has an Expert Sphere Grid. (Out of curiosity, do you choose this at the start of the game, or when you first gain access to the sphere grid in the story?)

3. PAL has 8 additional abilities -- Pilfer Gil, Nab Gil, Full Break, Quick Pockets, and the four Extracts.

4. Bribing requires twice as much gil in NTSC as in PAL.
