Decided to take a Ferry Civilians Mission after the tutorial, jumped into an unknown system on the way to my destination, found out it was a warzone, instantly blew up in the crossfire, killing myself and the innocents on-board. 10/10. Having fun.
Also I don't think you can sell cargo to a system unless it can also be bought in that system, tried taking Warhead Guidance Computers to a system listing it as highest price only to not see the option to sell them there.
thanks for checking it out! You are correct, at the moment you can only sell stuff in systems that also sell it, but I'd say the trading system overall is still a bit undercooked. The prices and distribution of goods is essentially random, and eventually it should be a bit more logical and you should be able to sell anything anywhere.
You can use the inventory tab of the in-game menu to mark the best known price (you only know prices on planets/moons/stations you've previously landed on) for cargo you're carrying on your map, to make trading less about guesswork.
I do also have some plans to reduce the likelihood of getting insta-wrecked on jumping into a system, mostly by making sure the player spawns somewhere that's relatively open and not right on top of a firefight. I may even mark systems as warzones even before you've discovered them, to at least warn you to maybe route around them
