I come up with the most clever ideas I could think about: how we should bring more action, aside of trading, to earn a lot of money?
FIRST. Since the GRN seems to be the main enemy to the Sirius, why not include the special credit chips onto killed GRN units - this would encourage players to go to Leeds and play as Kusari Exiles or BAF, and vice versa, put those credit chips onto BAF/KE vessels for profit to a GRN player. The bigger the vessel, the bigger value of the chip (let's say or 10 million for battleship.)
SECOND. Since the Liberty and Rheinland war goes on, the same idea of credit chips would apply to both LN and RM vessels. Just a bit fixed due to the diffrent scale of, actually, border war.

THIRD. In place of previous two, why not include a special payment system on the server - for the Navy/Police vessels - which would read, hmmmmm, spent hours or shot down vessels? Why I came up with that idea? Because players acts as the Navy or Police doesn't really get paid (or do they from the faction money?) It's a job, so why wouldn't players get paid for that? Shooting down, patroling and so on is also a job. It's not a mercenary, who get paid by a player-trader. It's not a pirate, who just stalk on the tradelanes and scare the traders.
