This game is good, but it is way over hyped. The story is a lot like the other GTA games. Go here and do this, or drive here and kill this person. There are some parts of the story that are very interesting and The game play is better the GTA IV and there are a lot less annoying characters. The best thing this game has going for it are the main characters, and the fact that you can switch between them. All of them have different lives and backgrounds and they all are interesting.
Overall, if you want a free roam game with new character personalities and aspects, and good character development, rent or buy this game.
