Guild Wars

Guild Wars was developed by ArenaNet and published by NCsoft. It is one of the few large MMORPGs commercially marketed with no monthly fee. An individual could buy the game at your local electronics or big box store and start playing as long as they could provide an internet connection.

Two related campaigns were later released: Factions and Nightfall. The original game is generally referred to as Guild Wars Prophecies. An expansion pack Guild Wars: Eye of the North was also released, though that requires at least one of the main three campaigns to be installed. Because characters can move freely between the campaigns after reaching a certain point in the game (assuming the player has purchased a copy of any campaign he wishes to explore), "Guild Wars" is generally used to refer to the overall game, and not to a specific campaign.

A great resource for any Guild Wars player is the official Guild Wars Wiki.
