Built for Competition - If you like Player-versus-Player competition, Guild Wars was made for you. In addition to building up a character by undergoing missions and quests, you can choose to create a character specifically for head-to-head PvP competition or guild warfare. The game is designed to reward player skill and teamwork, not time spent playing, so you won't need to spend hundreds of hours leveling up your character to compete.
The game includes integrated support for guilds, with the ability to create unique guild emblems, to acquire guild halls, and to keep in touch through in-game guild messaging. Guilds can challenge other guilds to battle, compete for control of key parts of the world, and be ranked on a worldwide ladder.
Heading Unique Streaming Technology - ArenaNet's unique streaming technology forever eliminates the concept of patching a game. You don't have to wait a month for the next big patch to experience new content. Instead, the game constantly and intelligently streams new content to your computer in the background while you play. The world can and will change continually.
