[Desert Rat]

If I have it right (please correct if not), the object is to trade for the resources that will give you seven of the Bonus Resources.

Asphalt
Automotive
Construction
Fine Jewelry
Microchips
Radiation Cleanup
Steel
and maybe even Scholars

I have two (Steel and Fine Jewelry) and need Technology >5 before I swap some resources to get Construction, then Asphalt and then Automotive. Need higher Technology before I get Microchips and Radiation Cleanup. I am limited by my starting resources as to how far I can go.

The following eleven resources are what you are looking for:

Aluminum
Coal
Gold
Gems
Iron
Lead
Lumber
Marble
Oil
Rubber
Silver
