As it celebrates its 20th birthday, online video game "World of Warcraft" has demonstrated a rare longevity thanks to its loyal following and constant evolutions.
"It is inspiring to be able to work on this rare game that has touched so many lives, and to also feel the burden of carrying that forward," Ion Hazzikostas, the current director of the game, told AFP at the Gamescom trade show in Germany in August.
