Bioshock is a video game franchise centering around the player entering a strange supposedly utopian city falling into disarray as its society breaks apart (Rapture, an underwater city isolated from the rest of the world free from governmental, religious and ethical control, and Columbia, a flying city theocracy embodying and literally worshipping late 18th century American ideals) run by a megalomaniacal idealist with twisted morals (Andrew Ryan, an ultra-individualist, and Zachary Comstock, an ultra-nationalist). Write about the political backdrops of the Bioshock franchise, analyzing what ideology each game is criticizing through narrative and gameplay mechanics and what is being said about them. Analyze the political messages implied by the cities and their inhabitants. What is being said about the political ideologies presented? What caused the downfall of the societies and how is it affected by their political systems?
