Bioshock

Another game I have enjoyed for so long goes by the name Bioshock. Based off of Ayn Rand's Novel Atlas Shrugged, Bioshock is about a city in which anarchy is declared rule, and chaos ensues. The idea behind anarchy was not to live a life without rules, so much as to prevent the government-placed inhibition of people's lifestyles, such as research and art. The game has graphic displays of how drastic our world would be without some rules in place to prevent certain organizations from carrying out ruthless acts and labeling them as "research" or otherwise. It also shows how impulsive people become when left with no outer restraints on their behavior, by performing violent acts, submitting to drug use, or committing any number of other crimes.
 Almost perfectly modeled for the time period in which is takes place, Bioshock has many similarities with the 1960's style of buildings. Taking place in an upper-class underwater city, the environment is perpetuated by the dark sea surrounding the metropolis, while neon signs and lights flash at the player as they navigate the corrupted city. Posters that are similar in style to those used in wwII are seen plastered all over walls, some covered in smeared writings of rebels and crazed drug users known as "splicers". In terms of sound effects, old radio songs can be heard almost constantly throughout the game, such as whenever a player visits a shop or passes by a phonograph.
I highly recommend this game to anyone who enjoys first person shooters or extremely thrilling games. The gameplay is highly customizable, with different powers (called plasmids) and weapons that can be upgraded throughout the game. The storyline is equally interesting, and has spawned many groups that debate over what certain symbols and meanings are within the game.

A warning: Bioshock is EXTREMELY graphic and contains some disturbing content matter (but for the brave, it is wicked interesting).
