It's Final Fantasy!
It fixes a lot of issues/flaws that I despised in FFXI (which I also loved and have played for over a decade)
The lore/story/world is beautiful and, more than that, I feel we the community are inadvertently influencing it's ongoing design and development in very subtle ways, despite what some people think (thanks to Ferne and the rest of the lore/writing/localization teams interacting with us players about the game's lore and worldbuilding)
Being in the Alpha and Beta tests, as well as a Legacy Campaign member, I feel I made a personal contribution to the game's development, even if it was extremely minor. And as my name is in the end credits (as part of the 'Meteor Survivors', a perk of being a Legacy member), I feel I have a much deeper, personal connection to this game than any other I have played.

But most importantly, this is Final Fantasy, a FF game where I can create my own character and experience the game's story through the eyes of my character. I'll love this game forever!
