Time, Money, Resources (TMR)

Amazing in how many games actually use this factor as natural banlancer, not to mention a fact of life.

Case in point:

Say you want to build a bird house for your backyard. First you have to go to the store and buy the wood, nails, paint and tools (if you don't have them) needed to do so. Then you build the bird house, paint it and nail it to a tall pole. And finally you have to put it somewhere in your backyard.

TMR Factors

Time: the time it took to buy the materials, make it and then place the bird house the backyard.

Money: the overall cost to make the bird house.

Resources: the materials needed to make the bird house.

As a fact of life, and gaming, TMR factors always has to be taken into consideration.
