so where am I going wrong? Most grateful for advice on how to ramp things up, both financially and how to get better trading / mission deals. Thanks to anyone prepared to answer.
Dear Lysander,
Welcome to the 'boards. You're not doing anything "wrong" per se. Thargoid has provided you with good information, but I'll try to add to it.
You've correctly determined that passenger runs aren't very profitable. But, they do offer the chance to get paid to see the galaxy, so later on they may provide a welcome break from your normal routines.
~Save your game often.
~Purchasing additional cargo space is mandatory for a Cobra Mk-III ship.
~If you plan to harvest fuel from a sun, be sure to equip your ship with heat shielding beforehand.
~Witchfuel Injectors enable you to decide "fight or flight". Without them, you may not be able to disengage from a situation.
Trading:
Find a profitable pair of systems near to each other (Rich Industrial with a high tech-level near a Poor Agricultural world). You want to make the most profit per tonne of cargo. So buy/sell items with large price differences between worlds.
~From Rich Industrial systems purchase Computers, Luxuries and Machinery in that order of priority. (Your ship probably won't have enough cargo space to buy all three, so computers will be what you buy most often.)
~From Poor Agricultural systems purchase Furs, Liquors/Wines, Radioactives, Food, Textiles and Minerals in that order of priority.
If the prices are right consider purchasing Gold, Platinum and Gems. But track the prices of these items for a while to get a feel for the good buy/sell margins.
As Thargoid mentioned, the missions will be offered to you later on after you've met certain game conditions.
The more credits you have available, the more expensive (and profitable) cargoes you can purchase. Some missions will expect you to be able to purchase and use a Galactic Hyperdrive (costing 5,000 cr.) on short notice. So build up your credit balance via smart trade runs.
Eventually you'll have more money than cargo capacity. This is fine. Around that time you may begin considering whether or not other ships will better satisfy your business goals. Figure out what you want and save up for the cost of it.
My first ship was a Cobra Mk-III. Later I wanted more cargo space and traded the Cobra in for a Python. (I used my Python to bounty hunt the Constrictor ship.) But the Python's slower top speed became a drawback. So, I saved up for the Boa Class Cruiser I'm flying now.
The mission I'm interested in tackling now doesn't trigger until after I've had somewhere between 1300 to 1400 kills.
I've already visited all 8 Galaxies twice over and now have a nice trade route in Galaxy 3 between two planets that are 0.0 light years from each other. (Nice find, eh?)
So, keep building upon your sucesses and honing your skills.
Good luck, Commander.
