I was way into ARG's... I played The Beast and Dave Szulborski's excellent "Chasing the Wish," as well as a few others. I also PM'ed (puppetmaster'ed, for those not up on their ARGonyms) Lockjaw, and I believe I wrote a puzzle or two for Urban Hunt. ARG's are a lot of fun and tend to be surprisingly innovative, though actively keeping up with their goings-on can quickly become a full-time hobby.
