Eurogamer's posted first details of Otherland, a dtp-developed MMO based on the books of American author Tad Williams.
It's out in 2010. As the site puts it:
Otherland takes place in a near future where the super-rich have their own private virtual worlds on the net, peopled both by AI, and unwitting humans who don't know that what they're experiencing isn't real.
The screens look bonkers. Take a look.
