Square-Enix's online RPG has a new wrinkle, as an awaited player-vs-player mode was added to Final Fantasy XI today.
Simulated battles can now be fought throughout Vana'diel, as its four nations have set up a board known simply as "Conflict" (International Resolution through Non-lethal Conflict). The first such Conflict is based on training exercises by the Royal Knights of San d'Oria.
