Even if I accepted what you said regarding the vigors as true, it still does not explain why they aren’t well integrated into the game, either in the setting, or in the gameplay. Outside a few sparse enemy types, vigors are hardly used by any of the other inhabitants of Columbia, yet you will see advertisements, salts, and pickups for them everywhere.
 
Things like that really strain narrative coherence.

@Ebalosus  
Actually, there was an explanation for vigors given in-game. Theres a building in Emporia where you can find Fink’s brother as well as a voxophone mentioning a biologist Fink was watching through a tear. The implication being that he’s ripping off of Dr. Suchong’s work. As to why it didn’t get a more detailed explanation, that’s because it’s not a focus of the story. It was likely added to the game for gameplay and/or marketing reasons.
 
As for the magical powers, people have them because existing in seperate parallel dimensions at the same time apparently allows you to see a different perspective or something or other. In short: a wizard quantum physicist did it.

Magic Space Booze in a game about a floating city and time travel? Will we explain it? Fuck no!
 
We don’t need to explain how certain characters have magical powers, because fratboys and casuals will eat this game up regardless of the quality!

I could totally see that being Fink, what he needs some good marketing, perhaps from a pair brothers who could open up a new opportunity.

I sure-as-shit hope not, since his writing is only a single step above Mac “the hack” Walters of Mass Effect 3 ‘fame’

Does anypony else think the vendor looks like Fink?

could be the bucking bronco vigor

Seems a bit like a stretcher but I see it.

Oh WOW!

It’s like they’re inviting Ken Levine to write parts of the episode. XP

Someone DID find the Luteces in this episode…
