The moment Niko arrives in Liberty City he is met by his cousin, Roman. This crucial relationship is just one of many you will develop while playing GTA IV. These friendships -- either with the rough and tumble men of the city or its lovely ladies -- evolve initially through the story. But it's your decision whether or not to pursue these friendships beyond the story missions. You and Packie McCreary can have a cold association with one another, but money will still ultimately bring you together. But should you go the extra mile and make Packie your confidant, you'll reap the benefits.
