This game is going to be amazing and I don't really know why. Final Fantasy 11 was the best MMORPG experience I ever had and it was all because of the experience. The dire and deadly run to Jueno at level 20. The terrifying pirate attacks as I traversed the sea below level 15. The Samurai hero as I defeated the Kraken on the same boat at level 75.
 
If Final Fantasy XIV manages somehow to keep that sort of user-grown progression and organic experience then they will, in my opinion, make the greatest MMORPG of all time.
