I'm a fairly new player, having played a couple of games now, and there is one aspect of the game that I feel really could be improved with a few small tweaks. This is, mainly, the trading economy. The economy of the game seems to be intended to be simple, which is fine. However, trading in this game is far too easy. When I first started, I went full in as a bounty hunter, which was rewarding, and very challenging. When I, later, started to do trading, I found the game far too easy.
The reason for this is simple: there are plenty of good trade deals around but very few AI traders who fulfill them. Hence, the player can very easily just run around fulfilling whatever trade he wants and making tons of money.
There should be many AI trader fleets fulfilling these orders as well and making money. This would make the game much more immersive, since, with all the money to be made, traders, smugglers and pirates should all be trying to get in on the game. It also would make trading more challenging as the player will really have to pay attention and be quick to get to the trade deals before the AI does.
Overall, it would be a really beneficial to add more AI traders to make a more immersive experience and to create more trade competition for the player.
