So of course, Black Crusade does not have the same acquisition rules as Rogue Trader or Dark Heresy, which makes perfect sense, as the Screaming Vortex and the shadowy underworld of Chaos of course would not have the thriving market economy that the Imperium does. However, it does occur to me that the Infamy system as written seems to overlook a few important factors that would come into play.
As written, Infamy centers on the idea of a character relying on his terrifying reputation, political clout and perhaps influence to demand both equipment and services from others. However, it seems to overlook, or perhaps just gloss over, the regular granting of tribute which has always been a big part of warlord-vassal economies; ie, a Chaos Lord dominates a region of space and lets everyone live as long as they continue to send in their tribute, whatever form that takes.
Then there is the question of loot: if a group of PCs go on a raid and manage to capture large amounts of throne gelt, or perhaps other valuable treasure like quantities of raw silver or gold or gems, then shouldn't there be some kind of a rule to recognize its value? Obviously some things taken in raids, like valuable cargo or slaves, would be handled under the rule of trade, but things like hacksilver and throne gelt don't seem to fit in.
Am I right in thinking so on the question of both tribute and loot? Would it be a good idea to write up a set of notes or side rulings to figure out how these things play into Infamy, or do the rules as written already cover these ideas? After all, one could suppose that passing an Acquisition roll on Infamy also counts as simply buying an item with wealth received through tribute, and letting the fine details sit in the background.
