It seems obvious, when you think about it. Activision/Blizzard recently announced that Zork Legends, a browser-based, presumably free massively multiplayer game! Now you can visit the Great Underground Empire with your friends, and reflect in live chat on the various inadequacies of the Flathead Dynasty, leading all the way up to Lord Dimwit Flathead and the collapse of his kingdom.
Zork’s natural silliness seems to lean well into MMO territory, as oddly-named players behaving badly is par for the course in that kind of game. Sources say that Zork Legends may one day be iPhone or even Android compatible, so you need never leave the GUE again. For Quendor!
