TL;DR

I suggest adding a commercial system.

What ?

In the space age, we may encounter other forces and engage in trade with them. Of course, there is no need to create a force specifically for commodity exchange. We can trade with some forces that we cannot directly contact (Void Trade )

Why ?

This can enable us to appreciate the important role of commodity exchange in production during the process of development.And this may be interesting and also adds new gameplay to the game

There(may be several) mods for trading... I don't really see the point of implementing it in the game. You can find it here

There were many suggestions around implementing a trading system, whether with an "NPC" faction, or between players on the same map, or even between maps. Didn't merge the threads, because all of them have different flavours :

Trading between players (not on the same map) :

A bit of all of them :

Thank you for your replies. I'm sorry that I didn't fully understand the previous post about this idea
