If you are easily offended by violence or foul language, don't watch any videos in this post, otherwise enjoy.
This game has amazing graphics and is one of my favorite games to play. You can see what I mean in this three video play list, which concludes with a 30 minute mini-movie.
The game draws heavily from both the plot and aesthetic elements of film noir, stylistic films made popular in the 1940s and 1950s that share similar visual styles and themes including crime, sex, and moral ambiguity. The game uses a distinctive colouring-style, but in homage to film noir it includes the option to play the game in black-and-white. Various plot elements reference the major themes of gum-shoe detective and mobster stories such as Key Largo, Chinatown, The Untouchables, The Black Dahlia, and L.A. Confidential.
There are more cases available as downloadable content for this game. Another favorite of mine with unbelievable graphics, as you'll see in this two video play list.

Mafia II is a third-person action-adventure video game. It is developed by 2K Czech, previously known as Illusion Softworks, and is published by 2K Games.
The game is set in the 1940s-1950s era of Empire Bay, a fictional city based on New York City, Chicago, Los Angeles, Boston and Detroit. There are 30-45 vehicles in the game as well as licensed music from the era. The game has three different in game radio stations, Empire Central Radio, Empire Classic Radio and Delta Radio, with licensed music, news, and commercials. The radio stations includes music from different genres including rock and roll, big band, rhythm and blues, doo-wop, among others.
Along with the other music in the games radio stations, Mafia II, to me anyway, has one of the best music scores ever written for a video game.

I used to have Mafia 1 for PC. I was able to utilize full creativity customising the vehicles in the game. I am unable to do that with the PS3 version I own, but the graphics, storyline and downloadable content make up for it. Here's another two video play list for Mafia II.
