The "Hemmed in a corner with no good access to plentiful resources" scenario:
Stop all unnecessary production of units and factories (within reason of course) and focus on developing your economy internally through the use of Mass Fabrication plants, adjacency bonuses, and collecting natural resources with your engineers (rocks and trees). Then branch out and take what should have been rightfully yours from the start!
If you've paid heed to the knowledge we've given you in this intensive two-day Boot Camp, you'll soon be on your way to becoming one of the most fearsome Supreme Commanders in the known universe. Dismissed, soldier!
