These do vary by type of system as well. I kept finding floating grain in an agricultural system rather than gold or other metals or minerals. Stolen grain just isn't worth the time spent chasing it with a fuel scoop. I still find gold sometimes but that will be in the anarchy systems. I also don't recall finding the rozzers and being scanned apart from in federation space.
I prefer pirates as they at least put up a fight and I don't get a fine when I kill them. Gold is fine too although at this point making money is so easy that it becomes unimportant.
yeah, i found out different type of crap floating in space, grain, explosives, toxic waste etc. etc.
this is what i have seen so far in USS:
– Canisters with different commodities, including Toxic Waste, Grain etc.
– Canisters with Gold (only in Anarchy Systems), sometimes guarded by pirates.
– Lakon Type 9 that if you attack him ejects canisters with toxic waste and tries to jump away;
– Lone merchant ship (sometimes will send comm to you that they are buying goods – just fly near to them with the correct cargo to make the sale);
– Lone Pirate or small group in Sidewinder/Eagle/Cobra;
– Group of 3 pirate Cobras (usually one cobra has many missile hardpoints);
– Group of pirates in Anaconda and Sidewinders;
– Group of police ships fighting pirate(s);
– Group of pirates attacking transport ship;
– Bounty hunters or local police ships scanning for illegal goods and bounties;
– Couple Eranin Sidewinders fighting couple Federation Fighters.
