Recommending GRAND THEFT AUTO IV to all of you crime buffs. Features the psychology of crime, a re-enactment of the Russian Mob's play for power in New York City a few years ago,and one of the most beautiful speeches I've heard in my whole life. If you like the storyline, try the Lost and Damned biker add-on. Skip the other. Mafia 2 was a bit of a disappointment for me. Here's a video.
