Random Fate Core thought of the day (abbreviated, just got home from the hospital with a newborn addition):

One thing I hear a lot from new Fate GMs is that they're worried about encounters being too tough for their players.

Knock it off.  Seriously.

One-shotting a character requires, for a character with Mediocre Will and Physique, a minimum of 23 stress.

So, really, that 6 Fighting NPC isn't going to make a dent.  Play hard, remember that it's okay to lose a fight, and let the Consequences and Concessions systems do their jobs.

(Now, I'm going to play with baby Faye, whose name is a lot like both Fate and FAE!)
