The Guild Wars 2 Website now features a "Dynamic Events Overview" where Lead Content Designer Colin Johanson outlines how quests will be generated in ArenaNet's upcoming MMORPG sequel. Colin describes two fundamental changes they are making: One is that you will not need quests explained to you, as you will be able to experience the situation firsthand (the example being a dragon attack where you see the dragon, rather than having it explained to you), and the other is the real consequences of these situations, offering an example of what happens if you fail to complete a quest properly. He explains the benefits of such an approach:

By building a world where you see and hear the experiences, Guild Wars 2 will evolve the MMORPG genre by making a game world that feels truly alive. The core of this evolution is our event system, which allows the world to dynamically change based on actions and decisions made by the players. A single player decision can cascade across a zone, changing the direction of a chain of events until they dramatically alter the content played by players in a map.
