I still have mine, still wish it would have had some in-game use.
The Waking Titan ARG was THE MOST bonkers game launch thing I have ever seen and when I try to explain parts of it ("We had to collaboratively solve puzzles to unlock a fuzzy image on a web page that revealed another inscrutable clue", "We sent an actual human to a random physical location to collect the next clue by hand"), I get gobsmacked stares.
