First, make a metal mine and a crystal mine. Then, make a solar plant
and a dueterium synthesizer and save enough resorces for a research 
lab. Next, either make a comuter technology or a energy one. Finally, 
save resorces for a ship and a ship yard. If you keep on upgrading 
and researching i bet you will have a death star in no time.

* Make a defense so you have protection for your planet.
