Taken from the review:
"Expectations were so high for Grand Theft Auto IV that one of the biggest surprises is that it's managed to meet them. That it's also gone on to confound these is truly a marvel, and the game's Liberty City is nothing less than one of the greatest videogame worlds yet conceived. With this game, Rockstar has set out to free itself from the excesses of the series past to emphasise the character of its world, and in doing so has created a high watermark in the relationship between narrative and play. It's no less than the definitive open world game, and by that measure the definitive interactive experience of this generation to date."
