The relationship aspect of Grand Theft Auto IV is perhaps one of the most nebulous areas of this epic game.
However, that shouldn't daunt you from building as many relationships as you can, because they happen to provide some of the deeper and more rewarding experiences Grand Theft Auto IV has to offer.
Niko Bellic, a veteran from the Bosnian war who struggles with memories of the horrors of war, migrates to Liberty City in search of a better life as well as to escape the memories of his past.
Sex: A lot of people think that there is tons of sexual content in this game. There is partial nudity at the strip club, but it is quite hard to find the strip club, and even if you do find it, you probrally won't even know that you can go in. The main character, Niko, dispises drugs and can't stand people who use them which makes his a positive role model. And btw this game is fantastic and has amazing graphics. Also this game teaches kids about landmarks and buildings in New York City.
If you land a few feet away and walk to the chevron, the helicopter disappears after Michelle leaves the house.
Note: This was not the case when I took the helicopter on some later missions that required cut scene triggers by crossing the yellow chevron.
There are two females in the game you must date—Mallorie's 'friend' Michelle and the O'Reary boys' sister Kate—but other than that, dating is completely optional.
However, there's a lot of fun to be had by partaking in the Liberty City singles scene.
