Units that cost power

Every unit has a requisition cost and power cost, which can be 0 or more.

For all races - except Necron - you can consider power to be a secondary resource, whereas requisition is a primary resource.

As a secondary resource, power income is generated: Primary resource is generated in a far larger quantity: The result is that power is a scarce resource.
 * By structures (with a cost) over time.
 * An initial surplus of 100 power.
 * By map control
 * An initial surplus of approximately 1000 requisition.

The usage of early game units with a this scarce resource affect your strategy as it changes: The more you reinforce, the greater the impact. Consequently, opponents can force fights with you, to increase the impact.
 * 1) how many gens you need to reinforce it
 * 2) how fast you can tech
 * 3) how fast you can economy boom
 * 4) how many researches you can use
 * 5) how many special weapons you can get

The impact of this is greatest in the early game, so that phase of the game will have focus.
