Anyone here play Aion? If you haven't play it, I highly recommend it! (｀・ω・´)

It's an awesome PvP MMO which you have to choose one faction and you can cross over to the enemy faction’s areas through rifts. And it has top graphic!

Forts are also areas of great PvP battles. At certain times forts become vulnerable and can be conquered by the two player controlled factions, Elyos and Asmodian, and by the third faction that cannot be controlled by players, the Balaur. The Balaur are at war with both player controlled factions and can interfere with PvP events regularly.
