Yes, you have lots of anmials around, they tend to eat dead bodies.

More fun you will create more dead bodies who has to be removed on cell reload.

Logically you will find skeletons in protected places like inside houses where large animals don't get them.

The stranded cars are for blowing up,

I guess it depends on distance from center and atomic yield. Not sure at what distance our fictional bombs would just completely destroy the human body to where there's nothing left.

Not going to say vaporized as that doesn't happen from my reading.

But simply put probably "Video Game" time constraints.

Maybe the raiders used the bodies as home decoration.....no, wait. Mojave, not Capital Wasteland (the most craaaaaaaaaaaaazy place in the Earth folks)

As far as bodies not being found near cars, there's an easy explanation for that: they walked away. If a person wasn't obliterated by the blast, they would likely have been well enough to move away from their cars. After all, if you see an atomic bomb fall, your thought process isn't "I should stay here until I die". You're probably going to be moving away from the bomb, either looking for survivors, or trying to get medical help (since you just got irradiated, after all). Staying where you are so someone in the future can find a skeleton near the car is a rather stupid move.

Also, bones do decay, just like everything else. However, certain conditions can result in them being preserved instead. Egypt, for example, tends to be very dry, so the bones get preserved, but there have been graves found where the bones had actually dissolved due to acidic soil. Now, Nevada tends towards the very dry, so preservation would be more likely, but since it wasn't hit as hard by the atomic bombs, wildlife would have still been active, so just because a person died near a car, that doesn't mean that their skeleton is going to remain there.

And decomposition would take care of the rest

Yeah also no skeletons in the Mojave in the cars. These Aliens must have stolen them from both coasts.

Think reaaallly hard about this question tonight as you're playing F4 and you completely obliterate all the raiders and super mutants while clearing a building. Imagine 200 years of fragging, miniguns, and fat boys.

edit: unless I'm misunderstanding you. are you saying, that because the inside is ravaged, the outside should be, too? Or are you saying, that since outside is undamaged, the inside should also be undamaged? either way, you can make perfectly valid arguments for both scenarios. I'm not sure why you think that's an issue

Re: buildings with intact exteriors and demolished interiors

Consider the havoc wrought by water and termites. The only reason we have floor slabs still intact is because they're constructed of reinforced concrete and galvanized steel, rather than wood cladding on wooden joists. The RobCo office building is no exception. Collapsed sections mostly where you have bathrooms or break rooms, with broken water pipes leading to the water damage we see.

My 2 caps, worth little in today's economy.
