A slideshow of failed tourist projects includes The Worlds project in Dubai:

The World Islands, Dubai

This artificial archipelago of small islands was dreamt up by Sheikh Mohammed bin Rashid Al Maktoum, the ruler of Dubai, to look like the map of the world. And his hope was to turn the World Islands into the playground for the rich and famous. Construction of the 300 islands — made entirely of dredged sand — began in 2003. But when the financial crisis in the real world, it brought production of this $14 billion-dollar fantastical world to a halt. To date only two of the islands have come to fruition.

It looks cool but it is hard to imagine (1) how much money and work it would take to finish such a project and then (2) who might purchase all of these unique properties.

But, if it did all go forward:

1. Who would purchase what spots in the world? Who wants the awkwardly placed Antarctica?

2. Does the development allow connections between the locations? How about bridges only where Risk lines are drawn?
