Guild Wars 2's data and design in detail
Happily for the Guild Wars 2 fanbase, he also asks much more practical questions, and he directed some of those questions at ArenaNet's Izzy Cartwright. He even got some answers! Cartwright talked about how ArenaNet's ability to track players led to the implementation of certain dynamic events, meant to split up the player population in a map, which would trigger when there were too many players in an area. Another benefit of the team's data gathering is the ability to see where players are dying most often in order to adjust content difficulty as necessary. The economy is especially dependent on player activity, and Cartwright says that the team keeps a very close eye on item fluctuations to be sure that a relatively healthy stat is maintained.
