This appears to be a very interesting publication www.spacetimeplay.org.

The richly illustrated texts in “Space Time Play” cover a wide range of gamespaces: from milestone video and computer games to virtual metropolises to digitally-overlaid physical spaces. As a comprehensive and interdisciplinary compendium, “Space Time Play” explores the architectural history of computer games and the future of ludic space.

Anybody got it already?
Hint: one of our keynote speakers is listed as a contributor…:-)
