yaknow, there was a ruckus about the unfairnessto the player and how the computer "gets more asteroids" but i think this cann all e solved by NOT getting gravity wells, because they send more asteroids to your opponent, and are really a waste of space.
front line-3-5 laser towers or refinery towers near any crystals
middle line-frag/blast towers and refinerie if needed
bottom lines are same as middle line, simple win just upgrade everything.
