What sparked our conversation last week was him getting hyper-focused (to an extreme degree) on how to make money so I can make my character better. And if you've played the FFG Star Wars system, you know that while there is a decent and fun gear mini-game built in, with extensive upgrades and component building, etc., it's really just a fun nice-to-have. It's not a core part of the gameplay loop in any particular sense, other than it does give the residual min-maxers something to idle on from time to time.
I'm going to Devil's Advocate a little here. Could it be that the reason the player is pursuing power upgrades is that they feel their character is underpowered?
I mean, look at A New Hope. The PCs clearly are Leia, Luke, and Han. These characters are
really badass.
Leia faces down Grand Moff Tarkin, and successfully bluffs him into believing the Rebel Base is on Dantooine (even though it doesn't help Alderaan). She faces down Darth Effin' Vader, and resists his torture droids. And once she's out of her cell, she is kicking all sorts of butt against the Stormtroopers who previously held her captive.
Luke might start out a bit
whiny, but he soon finds his footing. He's the one who gets Han Solo to tag along on the Leia rescue mission, he does an admirable job shooting down pursuing TIE fighters, and of course he's the one who places the one-in-a-million shot that kills the Death Star.
And Han Solo is a stone cold badass. He deals with bounty hunters like Greedo like it ain't no thang, he's done the Kessel Run in 12 parsecs, and he outmaneuvers tiny little fighter ships that are basically just engines with guns in his big honkin' space truck.
Starting characters in Edge are... not that. I mean, they're OK, but they're not Han Solo or Leia Organa. Could it be that your player just wants to get strong enough that they feel they can do the kind of stuff Han Solo does?
"Doyleist," as best as I can tell, is not a term that comes from the Forge or TTRPG jargon.
It's a term that originates in Sherlock Holmes discourse, with its counterpart being Watsonian. Basically, if you ask why something happens in a Sherlock Holmes story, you will get a different answer depending on if you're asking John Watson, the fictional narrator who will give you an answer within the narrative, or Arthur Conan Doyle, the actual author who will tell you why he chose to write the story that way.
Essentially, Doylist means out-of-universe and Watsonian means in-universe.
