Thanks, Dave. Yeah, in the video Ree is speaking about the player’s personal story, whereas Colin is talking about dynamic events. We like to think of personal story choices being permanent and dynamic event choices being persistent. The difference being persistent choices will remain until something comes along and changes them. So for instance, in the personal story you may choose to let an NPC die, that NPC is likely to be an important story NPC that the player feels some attachment to, their death will be permanent and will have repercussions on the characters story. This would be reflected in instances. In the persistent world a dynamic event might result in an NPC being killed. This will be a more generic NPC like a merchant or a soldier who will likely be replaced once some other event takes place.
Right, when Ree refers to, “players will kill a boss and they won’t re-spawn 10 minutes later,” she is saying when playing through your personal story line if you kill a boss, that boss will stay dead and your personal story will reflect this. It’s not really physically possible to make each dynamic event permanent, because the game needs enough content for everyone to play, and we don’t have 10,000 people making content for Guild Wars 2, event chains need to cycle and events need to repeat to ensure players have enough to do in the persistent game world. Our goal with events is to ensure that when an event ends, you feel like it actually has some sort of outcome on the game world for all players, if even for a short period of time, where traditional MMO quest in persistent areas generally have no affect on the world.
