This is definitely a good thing to keep in mind - Flavor or "fluff" is something the moderators add to the game to make it more exciting. But if Burbeting died by being shot by a crossbow, you shouldn't go looking for who mentioned a crossbow in the previous day's discussion. It's just part of the story we tell to add some spice to the game.
Likewise, in a cosplay game, you might expect certain roles to be powerful. So, for example, in Sorian's Ace Attorney game, Miles Edgeworth was an ordinary town player with no powers. The mods will sometimes meet your expectations, but just as often, we'll play off your expectations to confuse you.
My point is - pay attention to what people are saying and how they are acting. The flavor is neat, but it won't win you the game.
