- Character build up/history/relation
- Story (you feel part of the world and care for it. When the story ends, it sucks because it has ended)
- The World and its mysteries. I loved the fact that you fly around the world finding the secrets of the world that is not on the map (FFVIII, the island you fight Ultima at, IX where you get Zidanes ultimate weapon, etc)
- The bosses
- Working together with your team to take down enemies/bosses and not being able to do it alone.
