Laws of the Race Gods.
The FIRST LAW of the Race Gods is this: A motor has three (3) SPIRITS that MUST (yes, must) remain in all motors during their existence.
The SECOND LAW of the Race Gods says this: You can only allow any TWO (2) out of the three(3) GOOD-SPIRITS in your motor at any one time.
The THIRD LAW of the Race Gods says this: The GOOD-SPIRIT that is not allowed into your motor will automatically be replaced by an ANTI-SPIRIT, so as to keep the First Law in place ... 3 SPIRITS per motor.
The SPIRIT list:
GOOD-SPIRITS:
1) Fast - run like a rabbit on roids
2) Cheap - build for peanuts
3) Life - 200,000 mile warranty
ANTI-SPIRITS:
1) Slow - cant pass the icecream truck
2) Expensive - build a house for the same cash
3) Death - might blow-up on start-up
So if you want FAST in your motor you can only pick CHEAP or LIFE, you cant have both and the one you dont pick will be replaced by EXPENSIVE or DEATH.
If it is CHEAP you are after you will only have FAST or LIFE, but never both.
Should you want LIFE you will choose between FAST and CHEAP for the second spirit,, and that means SLOW or EXPENSIVE must be there to fill in the third spirit slot.
Please note: If you ever have a motor with two ANTI-SPIRITS and only one Good SPIRIT you must change motor builders or part supplier right away. They have a demon.
Look at the list of SPIRTS. Pick two, and accept the fact that the ANTI-SPIRIT will be there. These are THE LAWS of the RACE GODS (thunder cracks in the background) ...
FAST + CHEAP = DEATH
FAST + LIFE = EXPENSIVE
CHEAP + LIFE = SLOW
LIFE + FAST = EXPENSIVE
LIFE + CHEAP = SLOW
