Dystopian Political Themed Album + Nine Inch Nails (Trent Reznor) = Multiplatform ARG
I mentioned this on the sign up page, but I wanted to go further into detail.
In 2007, Nine Inch Nails released a concept album called "Year Zero," with lyrics and music representing the possible dystopian political future of the United States of America. Myself being a HUGE NIN fan, I had been following a forum community dedicated to NIN (www.echoingthesound.org) before the album had been released and found that NIN fans all over the world were finding leaked music via flashdrives found in random locations at concerts, artistic symbolism in the leaked music itself, and then a plethora of disturbing websites, video, and audio that had been supposedly leaked from the future.
I was following when actual video of a NIN secret concert and "Resistance" movement meeting (with a real speaker and realistic setting) being shut down and shot at by SWAT teams was found. A phone number was revealed, and when called, it "added your number to a list of potential threats to the dignity of the United States" (or something along that line; it was disturbing enough that I clearly remember making the call, the time of day and where I was).
And then tiny details about a sniper shooting at a baseball game, a pandemic bacteria used in possible warfare, and chemicals put in the water to "call the public" around the same time that visions of a "presence" started to be recorded.
Amazing, right? In-person, phone, on-line, and then, incredibly, if you actually discussed the findings in that very forum, your screenname appeared on a (fake) list of known terrorists as the culmination of the experience.
The whole experience pulls thousands of fans into this thick, troublesome movement to the point that fans themselves starting creating "Resistance" art and logos, even after all the details of the whole ARG was released.
This is an amazing example of an ARG gone right, where participants were lured into the story and learned something in an entertaining and interactive manner. Everything was linked; it was almost quest-like. You felt personally involved, moved, and even at times, a little scared!
I think that a great ARG makes you forget that you are actually learning and uses as many venues of communication/consumption as possible to make the learners feel more involved.
