It also has:
- A world map
- More locations and they can all be revisited.
- More cities and they can all be revisited.
- More NPCs that have names, back stories and unique dialogue.
- Over 1,000 side-quests.
- Over 2,000 items.
- Over 100 unique party members.
It's a shame it never came to the PS3. It's a much better game than both FFXIII and FFXIII-2 combined, IMO.
