Can someone tell me the meaning of this?
I read it but I don't understand what does it mean exactly lol.
You all are terrible. Anyways, Cami, to answer your question, that's essentially the theme of the BioShock games as is Elizabeth's revelation in BioShock: Infinite. Basically, no matter what reality you go to, there will be a man, a lighthouse, and a city. In BioShock (original), the man is Andrew Ryan, who was sick with the shackles of society and wanted to create a place where everyone was equal and their work determined their position, etc, etc, it was pretty similar to communism. The Lighthouse is what lead to the city. Using the original game again, a lighthouse is what contained the Bathysphere which led to Rapture, the city.
To use BioShock: Infinite as an example, the man was Comstock, the Lighthouse had a special "aerial" bathysphere, and the City is Columbia.
