Guild Wars takes the best elements of today's massively multiplayer online games and combines them with a new mission-based design that eliminates some of the more tedious aspects of those games. You can meet new friends in towns or outposts, form a party, and then go tackle a quest together. Your party always has its own unique copy of the quest map, so camping, kill-stealing, and long lines to complete quests are all things of the past. Within a Guild Wars quest you have unprecedented freedom and power to manipulate the world around you; with the dynamic quest system, your accomplishments have a unique influence on your future.
You'll never spend days playing, only to discover that the choices you made early have left you with a permanently uncompetitive character. The unique skill system in Guild Wars encourages infinite experimentation but doesn't allow early choices to limit a character. And you'll never meet new players only to discover that you can't play with them or compete against them because their characters are on a different server than yours; in Guild Wars, all characters live in one seamless world.
