Trollbabe and Alternative Maps
Immediately I thought of using a different kind of map: instead of a geographical map, you could use a network system map, and play a TRON-inspired variation of the game. But then it occurred to me that you could use other abstract relational diagrams as well. For example, you might use an organizational chart, and position your characters among the departments of a large corporation. But the idea I said first out loud was the one that John and Tony most liked: you could use a diagram showing the relationships between different TV shows, such as "All In The Family" and its spinoffs, or if you're really ambitious, the vast "shared reality" of TV shows that somehow crossover or connect to "St. Elsewhere". Each player points to a show and says, "my character starts there."
(Incidentally, don't miss Milo's completely unrelated post below this one. I'm posting right after he did, so for those of you who might only read the most recent post, scroll down a bit.)
