What sort of antimatter economy have you come up with to support shipping? I wanted to keep antimatter fairly rare in mine so even antimatter boosted drives were extremely expensive to fuel. Most ships used fusion torch or rocket drives with straight hydrogen fuel.
Antimatter lets you cram a lot of boom into a small package, so it leads to some interesting setting issues. At least fusion reactors and drives quit cold. Of course you can handwave this by assuming really good safeties on antimatter-using equipment, but you know at some point the PCs are going to try something...
P.S. Saw your blurb on antimatter, and the station locations make sense as does hijacking ships for their antimatter. This seems absurdly dangerous though if containment technology is not really reliable! Also, if the antimatter is worth more than the ship, refueling seems like a very expensive proposition.
