Just as an exercise I plotted out the attack on LA using the excellent resource
http://nuclearsecrecy.com/nukemap/ - and I wonder why the game designers had the Soviets attack as they did - for one the amount of destruction is way past the point of a "limited attack on oil facilities only" - for another its definitely overkill
The Nuke attacks are as follows:
Torrance, CA: Oil refining and storage facilities (.5 Mt).
Wilmington, CA: Oil refining and storage facilities (1.25 Mt).
El Segundo, CA: Oil refining and storage facilities (1.75 Mt).
Carson, CA: Oil refining and storage facilities (.75 Kt).
Plus the attack on March Air Force Base
Ok first question - if you are going after refineries why are they using 1.75 megatons? Thats a city buster not a refinery buster.
Second - look at a map of LA and the whole attack makes no sense to use that many nukes. The Torrance and Carson strikes are basically overlapping - either the Torrance or Carson strike, all by itself would have taken out both facilities quite handily, as the air blast radius overlaps each other - and you don't need the fireball to take out an oil storage facility. In other words the Soviets weren't taking out oil facilities - they were specifically taking out the city of Los Angeles
When you add it all up it takes out basically the area from the 10 to the 5 to the 605 and hits LA with 4.25 Megatons - again a hell of a lot more than just "the oil facilities were hit"
Given that level of attack I definitely now agree with those talking about the firestorm destroying LA - Glendale, Burbank, the Valley, Pasadena and Orange County would survive but in the basin itself anything south of the Hollywood Hills and west of the San Gabriel River would have been one huge firestorm and nothing but ruins - i.e. what you see in the Terminator movies
One interesting thing - even with that devastating a pattern, due to its location there is every chance the Inglewood Oil Field would have survived both the attack and the resulting fires
