Those searching for virtual immortality will be pleased to hear that a German company, dtp Entertainment, is in the process of bringing Tad Williams' near-future sci-fi virtual world to life as a massively multiplayer online computer game. 

Williams's Otherland tetralogy, which is comprised of City of Golden Shadow, River of Blue Fire, Mountain of Black Glass, and Sea of Silver Light, is a sprawling tale of friendship, family, conspiracy, and immortality, focused at its core on a secret brotherhood and the hyper-real, virtual reality network they have created to achieve their dark ambitions.

The books are definitely worth the read; we'll have to wait and see about the game.  But it was only a matter of time until Otherland-as-MMO happened.  The only question is, will it live up to the books' vision?

dtp's Otherland MMO is already in development.  The Eurogamer story links to some teaser screenshots.
