If we're imagining a game ala TOS Star Trek, who exactly is going to use Espionage on an away team or manning the ship during a ship-to-ship encounter?
Set skill lists (
what you know) are not as useful as as Approach (
how you do something).
You really don't have to reskin the Approaches at all. Using vanilla FAE works perfectly, but it does lend itself to the genre.
Example:
The Captain:
+3 Command
+2 Military / Operations
+1 Academy / Nature
+0 Sciences
Things like Espionage can easily be subsumed under Military if it ever comes up as opposed to a player putting ranks into it and because of the way others players might pull a story, the Espionage skill never comes into play.
Star Trek characters are supremely talented, cross trained, and it's never about
if they'll triumph, but
how/when.
