Can i buy and play GW Nightfall without having GW factions or eye of the north?

There are 3 campaigns and one expansion.


Nightfall, Factions and Prophecies are stand alone. You don't need any of the others to play. However, it is sometimes restrictive in guild activities if you don't have every campaign.


Eye of the North is an Expansion Pack. This one requires at least one of the other three :)
