Barter economy

Has anyone ever run a game with a barter economy?

I’m currently planning a single player race game with multiple factions operating under a ruling house that controls all fuel production, construction factories and shipyards.

I figure that build points are the best way of getting a base price for things but I’m not entirely sure how to value the different types minerals they will use to trade.

I’ve not really sat down to figure it out due to work but figured I’d ask here.

It will be difficult to implement this.

It is difficult to implement barter in the game. If you want to create your factions as separate empires, you will have to exchange resources between them through the transfer of ships/colonies. It’s quite tedious.

However, if they are just different planets of the same empire, everything becomes much simpler.

Yeah I’m just doing it within the same empire, I don’t like all the screen changing form multi race games.

I want the different houses mostly competing economically and can figure something out for skirmishes later.
