I have never played a game that I enjoyed this much in all my life.
The graphics are great, not nearly as pretty as WoW, but the gameplay and substance make up for that.
The questing isn't nearly as tedious as other MMORPGs that i've played, which puts this game at the top of my favorites list.
Interacting with so many people, helping and being helped by so many players, and the overall social aspect of the game is just amazing. No game I have played, to date, can even compare to the social aspect of FFXi. It's unbeatable in that field.
The motivation to keep me playing is incedible. There are so many things in-game that make me want to keep signing back on. And the fact that I can change jobs, without losing my overall progress in the game, is just supreme over any other MMORPG out there.
Then the user interface. I love it. It reminds of the older FF games, but modernized for MMO capabilities. It is extremely easy to navigate once you get the buttons down, and making your own macros is just an incredible asset in this game.
I'm addicted to this game. And I hope many more people join the ranks. Now with the release of the 360 version, I'm seeing a lot of new faces, and I welcome them all.
Long days and pleasent nights.
