On that topic, Tim, I've been thinking as well (tell me if I'm too OT for the thread!). Sure, it's a good way to view AW that "everything and everyone" is a threat, but I keep thinking about the thing on the Fronts playbook: "Threats are people, places nad conditions that (...) threaten the players' characters." What if they only concern themselves with one of the player's character? What if they, and this is probably the worst that could happen if you do the "everyone's a threat" thing right, threaten different PCs in different ways? I mean, if an NPC hired gun is hired by the hardholder to root out the hocus' cultists, sure, he can be a threat to both, but in different ways, and his countdown clocks probably say different things.
For our hack, we use Stages with different agents involved rather than fronts. But then again, AW is unique in that the setting makes someone's existence be a threat to you inevitably, since there's got to be something you can't both have. Scarcity.
