@VIPER:
I am unfamiliar (British understatement there) with the narrative mechanisms of Compelling or any of the other.
An
Invoke of an Aspect allows you to use it to your advantage. Mechanically, it allows one of three things
(player's choice):
- It allows you to re-roll a roll and take the better result
- It allows you to add +2 to the roll you just made
- It allows you to introduce or discover a "new" fact about the current scene, story, setting etc.
That third one is the one we're going to talk about here...
A
Compel allows someone else--usually the GM--to use that Aspect to introduce plot complications.
An Example:
You have an Aspect
Wanted By the Galactic Authority.
Invokes:
You could
Invoke it (to your advantage) by saying something like:
"Hey, GM, I want to Invoke Wanted By the Galactic Authority to say that there are wanted announcements being displayed on the station feed and that the leader of the gang we need help from has seen them, so of course
he can trust me!"
The "facts" being introduced by this Aspect is the wanted announcements
and that the leader of the gang has seen them. If I
Accept this Invoke, you spend a fate point and the fact is now a part of the story. We then create an Aspect for the setting
Wanted Announcements, which you get a free invoke on.
Compels:
I could
Compel it (against you) by saying something like:
"Normally you would go to the market look for anything to help your pilotting rig. But you are Wanted By the Galactic Authority, and there's a small unit of GA-agents there, having just come off a deep-space duty. They haven't seen you yet. Will you accept this complication?"
The "fact" being introduced is the presence of a Galactic Authority unit on the commerce station you just docked with. So, we'd introduce a new Aspect to the session "
GA Deep-Space Unit Looking to Blow Off Steam. Nobody gets the free invoke 'cause I gave you a fate-point for it. Or, I guess, I get the free-invoke.
The Underlying Rule:
When you
roll dice or
spend a Fate-Point to create a new Aspect, you Always get a free Invoke on that Aspect. You can give that free-invoke to others.

Tagging An Aspect?
I will also accept/understand the expressions "tag an Aspect" or "tagging an Aspect". These means either Invoke or Compel, depending on how it's used. This is a holdover from The Dresden Files RPG (pre Fate-Core), which I ran for many years.
