Gamepyre published a review of GTA IV on the Micrsoft Xbox 360.

Quote from the review: "What I'm trying to say is this, the first several games weren't made for kids, and this one isn't either. Rockstar realizes that adults like you or I want to play a game that isn't bubbly and happily pointed towards a five year old. I want to play a violent game, I want there to be explosions, swearing, and even some prostitutes. And from the sales, it looks like I'm not the only person who thinks this.
As of the time of the writing of this article, Grand Theft Auto 4 has made it into the Guinness Book of World Records, just about doubling Halo 3's first 24 hours of sales. Not only that, but the game now holds the record for first place in the first 24 hours of release sales in the entire entertainment industry. "
