Do a gold rush version. In con struc 4.
This is a great game. Loved construction simulator 2 and paid the £4 for construction simulator 3. Smooth game play. Loved the few additions like the hole drilling machine, great. If your looking for ideas on the 4th one. Watch Gold Rush on discovery. You could do a gold mining version with the dozers stripping pay dirt, trucks moving over burden. Then setting up the wash plant and the money you earn comes from the gold you mine. But this is a great game. If you like trucks, building and driving machinery, I think this is hard to beat.
