One of the many things that set GTAIV apart from its predecessors is Liberty City, which is more convincing as a living, breathing urban environment than anything that you've seen in a game before, and bears little resemblance to its namesake in 2001's GTAIII. Liberty's diverse population believably attempts to go about its daily business, seemingly unaware that several criminal factions are at war in the city. Niko has no such luck. He's compelled to start working for one of the factions shortly after arriving, when he learns that his cousin Roman has some potentially fatal gambling debts. Niko's military experience makes him a useful freelancer for employers in the business of killing each other, and though his reluctance to carry out their orders is often apparent, he does whatever is asked of him in the hope that completing missions for other people will ultimately give him the means to complete his own.
GTAIV's Internet is filled with spoofs of all the kinds of Web sites that you'd only ever look at accidentally or when you know there's no danger of getting caught. Some of them can be found only by clicking on links in spam e-mails, whereas others are advertised prominently on the search page. There's plenty of amusing stuff to find if you spend some time in one of the "TW@" Internet cafes, but the most interesting site by far is an online dating agency through which you can meet women who, if they like your profile, will agree to go on dates with you. Dating and socializing with friends is something you can spend as much or as little of your time doing as you like, and though the people you meet can occasionally be demanding to the point that they become irritating, keeping them happy invariably benefits you in some way.
