Let's say that on my Turn during this Exchange I want to Create an Advantage: I Know That Fighting Style! - I spend my turn observing the opponent's fighting style. This takes a little bit of time to achieve, story-wise.
Mechanically, if the action succeeds, the Aspect is created immediately. Will my fellow players be able to invoke it immediately, even though it might not make sense story-wise?
I come from simulationist RPGs and I'm still wrapping my head around Fate Core. In Pathfinder, rounds are defined as 6-second fragments, where everyone's turn kind of happens at the same time.
Mechanically, in Fate you'd have access to this advantage immediately, but for it to make sense you'd have to at least wait until your next turn to use it (representing the time it took to observe your opponent), and consider communicating it to your fellow party members the exchange after that for them to take advantage of that new Aspect too (representing the time it takes for you to convey to your friends what the enemy's weak spots are).
Am I overcomplicating it?
