Ship hull panels are manufactured on leeds,
Engine components can be bought from the zoners or liberty,
MOX is manufactured almost exclusively on LD-14 (so in actual fact, you have to come to us)
Diamonds can be bought from the hessians (yes, hessians)
Anything i missed?
Ship Hull Panels are also manufactured on Belfast Production Facility! Buy from the Mollies, get a quick guinness in you!
Bretonian MOX and Rheinland MOX are separate commodities, which sell for different prices across Sirius.
Blood Diamonds are not a nice commodity to carry! If you're holding them, why are you worrying about tax in Rheinland? You're a smuggler!
Malexa, you raised the possibility of joint custody of O3 with the BAF. This is something I mentioned in the Bowex skype as a possible selling point for the whole tax system. If the Rheinland Military are taking down the OPG (and assorted other corsair/red hessians(though I've only seen one RH actually pirate in all my time on the Muldenkipper.. respect, "RHA"!)) then a valuable service to traders is provided.
The more often pirates die to RM/BAF efforts in O3, the more they stick to the deeper Omegas and attack Cryer/Zoner shipments. The more money Zoners lose to Corsairs, the more likely they are to look longingly at the Houses for trade.
Any change in player behaviour (disregarding a change in game mechanics) takes time, so don't expect the hordes to descend after one week. But after a month of a clean Omega3?
