IGN UK has given Grand Theft Auto IV a 10/10 - the first such rating to be given in almost ten years. In addition to the IGN UK's review, USA IGN review also gives Grand Theft Auto IV a 10/10! (thanks gta4.net)

- GTA taken to the next level - in a sense of technological progression and also sophistication.
- Liberty City is a gem to behold. New York expressed in a true Grand Theft Auto style.
- A level of integration between the soundtrack and the dynamics makes this a true "living, breathing city."
- The game deserves the highest score IGN can award, because it doesn't fail to push video gaming to another level.
- Storyline involves morality choices faced by players, giving way to alternative plot endings.
- One of the best integrations of multiplayer in a game, that the reviewer has ever seen.
