Bioshock - This is Rapture. A secret city beneath the sea. Set in the 1950's era, it homes some of the worlds elite in varying areas of expertise. People can follow their obsessions without repercussion. Artists would not fear the censor and scientists would not be bound by morality. With a political struggle and crazed, genetically "enhanced" citizens, it fell into chaos. Futuristic weapons and tech, magic-like powers, thrown into a noir/steampunk theme. Here we see the place prior to ruin.
