GTA IV is richer, deeper and more involving than its predecessors. By the time the story threads start to tie up, the mission trees shake out, you're totally invested in the characters and their world. I'm actually jealous of everyone about to experience it for the first time. The greatest testament to GTA IV's brilliance is that I haven't been able to stop thinking about it since putting the pad down. [May 2008, p.88]

I could go on and on about why Grand Theft Auto IV is one of the best games we've ever seen and why even folks who are easily offended should play it, but that would be pointless. The only thing you need to know is that you have to play this game. Period.

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.

The light cast across the spectacuarly detailed facades, the slick road affecting car handling and causing footsteps to kick up splashes, the imposing skyscrapers, the flashing neon, it all changes wiht each passing street, and weather system...That's what you'll take away from GTA IV, along with the multiplayer gift that will keep on giving. [June 2008, p.36]

None of these little flaws take away from Liberty City's breathtaking vistas, incredibly varied scenery, and lived-in look (the PS3 version has the slightest visual edge, plus motion-control support -- but then it's missing Achievements and the eventual downloadable episodes exclusive to the 360 game). The city just feels alive.

It's not flawless, and it probably won't change your life, but GTA IV is an absolutely amazing piece of entertainment. It does things that no other game does, it's immersive in ways that no other game is and it's one of the biggest, wildest, most enjoyable games we've ever played.

Although its got plenty of excellent features, it's ultimately the storytelling that makes it an instant classic, a game unlike any we've played before. As is the case with many great books and movies, you'll want to know what happens to the characters after the game ends, and one can't help hoping that all of their American Dreams comes true.

I now know how film critics felt after screening "The Godfather." It's been days since Grand Theft Auto IV's credits rolled, yet I can?t seem to construct a coherent thought without my mind wandering off into a daydream about the game. I just want to drop everything in my life so I can play it again. Experience it again. Live it again...Grand Theft Auto IV doesn't just raise the bar for the storied franchise; it completely changes the landscape of gaming.

After more than 40 hours Rockstar's most ambitious game to date was over and left me wondering if I'll ever be able to look at 'normal' video games in the same way again.

GTA IV is the best action game ever. The game has beautiful details, nice situations, extrodinary gameplay, sharp humor and great graphics. There are certainly a few minor negatives about the game, but the positive points are just too much. We have one piece of advice: Buy!

A masterpiece from both a technical and storyline standpoint. You have not and probably never will play another game quite like it again.

The single-player game, which you can still play long after you complete the story, is the series' best by far, and the multiplayer features are good enough that you'll likely have no problem finding people to play with for many months to come.

The important thing is that after many years of frustrating missions, driving back home to save repeatedly, struggling with wonky physics, and dealing with farcical storylines, GTA IV has delivered a polished and almost fully renovated experience with a darker and more mature treatment of the subject matter.

With only the most insignificant flaws remaining, Grand Theft Auto IV is a triumphant epic that no other developer could ever create. Designed with unrelenting passion, the series has categorically set the standard for the coming years.

Without a doubt, rest assured this is the best game yet for this generation. The only reason we've resisted giving it full marks is that in the same way GTA III?s template was blown out so much further in "Vice City" and "San Andreas," we?re confident the next GTA on this generation will up the ante considerably.

Almost everything you do in Liberty City would be good enough to drive its own game, and the best parts would be good enough to outrun the competition, but the reason it works so well is that Rockstar has made a game that requires no patience to play. This, as much as its usual coherency and the best script in the series, is what makes GTA IV the best openworld game yet, and why it will take something miraculous to rob it of game of the year status.

The very nature of the American Dream is the central theme in Rockstar Games' Grand Theft Auto IV, a gaming masterpiece that is a picture-perfect snapshot of the underworld of today's big cities. This is not only the finest title of the generation thus far, it is one of the best games of all-time.

It's amazing that a sequel that keeps the core gameplay concepts of its prior incarnations can do so much to change itself into something new. Cabs are awesome, as is the cellphones capabilities. But perhaps the biggest innovation is the notion that you can create a game that's as valid a piece of art as any book or movie. Is this our "Citizen Kane" moment?

Grand Theft Auto IV lives up to its grand expectations by weaving a Hollywood-ready "American Dream" plotline with a finely-tuned game experience -- taking the tried-and-true GTA formula and plugging it into a living, breathing version of Liberty City.

Considering the fact that it's been a target of political and media pundits who keep harping on the infamous "Hot Coffee" incident, it's understandable to think that Rockstar might tone down the adult themes in GTA IV. But thankfully, that didn't happen. This is a mature game, and a devilishly good one at that.

With so much to see and do that even months of play won?t cover it all and some of the tightest mechanics seen in a modern game, GTA IV is every bit as good as you could ask for it to be. You quite simply will not need another game this year.

Rockstar have surpassed themselves, delivering unquestionably the definitive GTA and perhaps the greatest videogame of all time. [June 2008]

Grand Theft Auto IV is the sex, drugs, and rock and roll of video games. It's a little less brave and intimidating this time around, but it?s also the most refined and polished game in the franchise?s history. This kind of sheen is generally reserved for titles with a much smaller scope.

You cannot fly a plane though. But with the amount of stuff you can actually do in this game, mentioning something like that would be like complaining about the frame color on a Picasso painting.

From the thankfully-revamped shooter interface to driving sequences that aren't out to simply punish you, from Hollywood-level cutscenes with great characters to a difficulty level that mostly goes up smoothly rather than in massive jumps, this is simply a better game than before.

The cut scenes are where the game really shines for me. There is this...this intensity in the character?s expression. Characters are actually emoting and expressing. They bring out emotions in us.

In the case of GTA 4, I think there's a little bit of over hype and expectations being overly high, but when the finished product is as good as what's on offer here, then it's satisfying that GTA 4 certainly delivers a full and rounded package that will please the vast majority.

If it were up to us, we'd have included a few better missions, weapons, and cars earlier in the game - if only for a temporary taste. That would definitely improve the pacing (while leaving plenty of surprises for later), and it'd have ensured that ADD players don't stop early without seeing the brilliant content that's down the road. [June 2008, p.40]

Coming back to our original conundrum, GTA IV has its flaws as a game, like the sometimes problematic auto-aim shooting or the massive difficulty jump when you get to the final ten missions. But as an all-round experience it's truly, hype aside, a standout experience of gaming in 2008.
