Any help with finding the ui font?

Chalet London 1960  Sugerido por thafitos 


Franklin Gothic  Sugerido por steelsmiter 
Helvetica Neue 45 Light  Sugerido por SirParadox 

Of the fonts already on my system, I found Franklin Gothic Medium does well to emulate it for the RPG manual I'm writing... although you might want light if you can find it.

Grand Theft Auto V’s UI font is called Chalet London Nineteen Sixty.
