Has a lot of similarities in the story line, except you end up fighting robots that were developed by the Army and are controlled by a super computer.
In fact some of the people and things that pop up in Fallout 2 are from Wasteland.
It sounds like it was probably influenced by TSR's Gamma World game. There is an old (I want to say famous, but that's probably not true) Gamma World module called The Legion of Gold
. Its about a mad computer that is sending an army of robots to attack the surface world from its hidden underground base.
I've also moved this thread to the Computer & Consolue Games section. I think you will get more replies to your topic now. As I know that the Fallout series is a favorite of many games (even me).
So maybe they have heard of Wasteland as well.
The game designers themselves know these values are not realistic and they do not intend them to replace or invalidate the fluff. So let's get on with our lives and not fixate over the cosmic ramifications of game mechanics which we already know are streamlined for larger forces at the expense of detail.
