yes i do, from recycling but nothing seems to be shipped out
I think you need another region thats willing to buy. If no other players have developed major infrastructure like you you're most likely screwed.
Every map needs at least one ai controlled city to work with you till others join in. Another reason multiplayer is a bust.
Actually, you do not. I I am in a private region with only one city so far. I export a great deal of alloy, plastic, metal, and coal from various sources. From what I understand they are sold on the global market. As to the specific factors that go into determining the global market price, I haven't the slightest idea.
