Id's Rage game is planned to be released some time soon and had people talking about how Borderlands and Rage are very similar game ideas.
But if you go back in time to the originators this concept and story idea was existing in the mid 1980s in a few computer video games.
there are two games i can remember playing in the Apple II system
It was a turn based strategy game that took place in an post-apocalyptic future you would scavenge stuff and build your character while traveling around an area.
a RPG set in the future where you would build and modify cars to battle in arena win money to get better parts and fight more battles
these games got there inspiration for a real dice roll playing game
and that game got it's idea from books and movies, with the gaming style coming from the mother of all RPGs Dungeon and Dragons.
