I wanted to clarify the Perspective Marker real quick. While I have control of the narrative, which characters can I make perform standard actions, like Achieve or Murder? Is it:
A) only the character with the Perspective Marker,
B) anyone in the same location as the Perspective Marker, or
C) anyone in any location?
My first guess would be anyone in the same location, but the only rules that explicitly mention the Perspective Marker are Relocate, and a few specific Plot Book actions like Intent to Kill. There doesn't appear to be any mention of which characters can perform Actions while narrating, and "primary point of focus" doesn't necessarily mean things cannot happen elsewhere. It's not unfeasible for a murder to happen off screen, for example.
On the other hand, a Plot Book like The Detective's Trial seems to imply that only the character with the Perspective Marker can perform actions. It only says that other players cannot place the Perspective Marker on the Detective, but the implication is that other players cannot control the Detective at all. Others not being able to Achieve with the Detective makes some amount of sense, but not being able to even Influence the Detective seems surprising.
From what I've read, the game seems very fun, but I think it would benefit from being more clear about which Actions can be performed by/on who, and what exactly the Perspective Marker means mechanically.
