Traveller, for example, will be well into its stride and firing on all cylinders - some books here we have already talked about, such as Supplement 6: Pirate Fleets, which does not just feature pirate-type ships, but gives you everything you need to run your own band of ruffians (and is non-OTU specific, so you can use it for Raiders in Babylon 5 or perps in Dredd, as well as you can in the Marches).
