The Lost Cities (2017)

The Lost Cities is a mod for Minecraft that allows the player to play in an old abandoned city instead of the normal overworld. You spawn in an old and partially destroyed city that takes over the entire overworld. There are highways, bridges, tunnels, a subway system, tons of dungeons with spawners and loot, and so on. There are also various configuration presets (called profiles) to alter how the world is generated.
