There is still a UCAS Dollar, a CAS Dollar, all kinds of CorpScrip, etc.
The lack of fuel economy or range for vehicles somewhat bothered me, as a GM. I see the modification for additional fuel tanks in Arsenal, granting an additional six hours of operation each, but I'm not sure how long the standard of operation is to start with, nor how far that will take me. I generally just eyeball it, myself, and have some houserule Lifestyle elements to account for fuel costs (either a new category for Gear Maintenance, or a Quality for Aircraft, etc)
