Denizens of Vana'diel will be glad to know that the latest update for Final Fantasy XI (PC, Xbox 360, PS2) is now up and running, and should provide you with new content and opportunities for fun!
While the full details are rather long, there's one notable addition that should make playing with your friends more challenging. The level-syncing feature is now up, and it allows higher-leveled players to power down their character and gear to a level appropriate to that of their lower-leveled friend. They can then undertake quests at that level and, in turn, earn experience and reap the benefits of friendship!
The full details behind this latest update and the level-syncing process can be found in the source article. In the meantime, you might want to go online and update your game.
