Chapter

A "chapter" or "campaign" is what the developers of Guild Wars, ArenaNet, call a major expansion of the Guild Wars game series. Each chapters is stand-alone and has to be purchased separately.

ANet plan to release two chapters per year, and each chapter will have a development time of about 1 year, which means the development is overlapping and dev teams are staggered.

Each chapter will add large amounts of new content, but will also include content from the previous chapters (common core content for all chapters).

Chapters so far:
 * Chapter One: The original Guild Wars, a.k.a. Guild Wars: Prophecies, released April 2005
 * Chapter Two: Guild Wars: Factions, to be released Q2/2006
 * Chapter Three: in development since November 2005, title unknown, release date Q4/2006 (unconfirmed)
