I Dunno, it sounds like the crazy reality based love child of Second life and Playstation home.
There is a market and (for some) a desire to participate in digital worlds, whether fictional or otherwise, but these environments are often considered more recreational than valuable user interface.

The user generated aspect shows potential, but when you consider the massive factual deficits in user generated sites like Wikipedia, whats to stop participants from creating a massive todger shaped eiffel tower?.

Another concern would be branding and the obvious desire to monetize such a platform, in its attempts to sustain itself will it sell out?

Only time will tell.

When I recall my favorite old games from memory i almost always remember the manuals of the classics before the cover art or cartridge etc.

The F-Zero pic really brought me back to my 12 yr old self imaginatively creating a whole melodrama with complex character relationships based on a two page comic book spread at the front of the manual.

As a kid the manual was the only thing that kept me sane while traveling the distance between the game store and my console.

An often overlooked necessity.
