1. It's FINAL FANTASY - specifically a FF game where I can create my own FF character and play through a FF game as that character.
2. Story - I love the story despite some slight early filler and plotholes. And the many twists and turns are keeping me guessing and theorizing.
3. It fixed everything that was wrong with FFXIV 1.0, and actually improves considerably on both 1.0 and FFXI - in particular most of the game is soloable, especially levelling.
4. My friends and family joining me - it really is better to play with loved ones.
5. Pretty dresses! It's true - glamour is the true endgame!
