A couple hole's I found is that the buildings look more like a warzone than decomposing with age. It was supposed to be an atomic war, not a war with a couple nukes thrown in. The big nukes would blow a big area up (ground 0) then not touch anything and kill with radiation for miles around. Then you would have any plants which could survive the nuclear fallout overgrowing everything. The end of the mall has nice fresh cut grass on it. Who mowed that? After 200 years with noone cutting back anything an not trampling over everything, it would be all overgrown. If there were no plants, there would be no air and everyone would die.
The world would be dirty like it is, because it would be so much bigger with way more stuff in it and about the same amount of people looking out for themself not starting up cleaning businesses. They would rumage through stuff take what they want and leave; not tidy up the place...
Another thing is all the mutants/gouls. Those are totally unbelieveable. Should just be a bunch of nothing with a few radroaches thrown in. Kinda like I AM LEGEND without the zombies/dogs. Just roaches. The only people who should be around should stay next to the vaults and build civilization around them. The climate would be all screwed up, so we would probably live underground in the vaults and create more "vaults" and probably just a vault world with them all linked together.
As the vaults would be a dimly lit world since birth. The only people who would live "top-side" would be the criminals (kinda like how austrailia started). You would find shelter from the sun as your eyes would hurt from being outside and it would be so hot. People would only come out at night, and the people outside would really only lookout for themselves as they are living in a world of only criminals. And they would have a hard time meeting people/reproducing so after the first generation, 95% of them would be dead.
There are not enough skeletons around as this was supposed to be a highly populated area. The deaths from nuclear fallout would be sky high, yet there is only a skeleton here or there. (Maybe the people who are supposed to be cleaning up everything for everyone also collects the skeletons and throws them in the ocean! lol)
gawd. Up until nuclear war is the only "believable" part of the fallout storylines to begin with. Energy weapons can exist with ammo everywhere (probably from the aliens who came down while everyone was in vaults.. :rolleyes
but we can't have an old ass appleII computer with power?
as far as fallout2, I'll mention something that bugged me early on in the game that is along the lines of what you are complaining about. When you climb down into the rat caves, how do you see? Rats don't need lights down there, The people outside have it locked off so they wouldn't light any lights. Why are the lights lit down there?
