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 must be purchased separately, but doesn't require any other versions of Guildwars to play.

ANet plans to release two chapters per year, and each chapter will have a development time of about 1 year. (This likely means that there are two separate teams working on expansions in a pipeline.)

Each chapter adds large amounts of new content, but also includes common core content present in all chapters.

Chapters so far:
 * Chapter One: The original Guild Wars, 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)
