I remember following live updates on R*ddit. It held all the tension and spectacle of a breaking-news emergency, except it was GOOD and FUN. When they found the cake, and then they reported what happened next, I ascended to nerd nirvana. It was magical. MAGICAL.
I didn’t get to play, really - I live in a small market these things don’t reach so by the time I find out about this stuff it’s over. But I remember a scavenger hunt that led people all over their city and wound up at a preview screening of the opening bank robbery.
