Can only be added when multiplayer is done. You create an galactic market and then can trade with all players who play factorio. (Without starting multiplayer match)
You set up a trade. Lets say 10 iron plates. It gets stored on the server, and players who have access to internet can see it, and give something in return. The next time you play on that world, you get a notification that you order has been furfilled.
Seems like a nice feature
