Easily the best game (on any console) to date, and probably the first true next gen game.
MGS4 is, without a doubt, Kojima's best work to date. It eclipses the first three games in every way possible without detracing anything from them. In fact, Guns of the Patriots elevates the previous Metal Gear games to a new level awesomeness by unveling their mysteries and cascading them in a brilliant light of clarity.
That said, MGS4 is in a league of its own. The story is immaculate, and it is told and captured in an impeccable manner. Not only does it conclude (and/or clarify) the life tales of the most prevalent characters in past games, it progresses in its own right with its own (new) characters and with its own plot twists. There is never a dull moment.
The story is only punctuated by the phenomenal gameplay, which has gamers on the edge of their seats at all times. The dynamic battle field provides a realistic sensation of war, which is critical to the plot of the game. But, there is such a great variation in tactics and gameplay that the gamer is never stuck doing the same thing for too long. In addition, the controls are smooth and intuitive. Any better, and you'd actually be in the game. This is saying a lot given the huge variety of things you are able to do in MGS4.
Graphically, Guns of the Patriots is hitherto untouchable. With action-packed cut scenes that could blow any AAA Hollywood flick out of the water and an ingame engine that could force the likes of Call of Duty 4 and Uncarted: Drakes Fortune to quiver in fear (or bow in respect), it is by far the best looking next-gen game yet. The environments are beautiful, and the characters look and move better than anything seen in a videogame so far.
Overall: *Character development is spectacular. You will love, hate, be disappointed by, laugh with, cry with, and enjoy beating the crap out of these characters. You grow with them. You understand them. *Enemies: This is a stealth game. But you have the option of fighting your way through. There are places where you have no choice but to fight, but whenever/whereever you do...you have a variety of enemies to choose from and an even greater variety of weapons to kill them with. * Replay: I pity the fool that ever played a MGS game once! You simply cannot get it all the first time around. And besides, there are so many rewards and extras worth going back for. You'll be playing this one at least five times. * Quality: A great story. A graphical powerhouse. Unbelievable sound. Excellent gameplay and controls. Not to mention MGO. If I had to pay for this game twice, it would still be worth it. It is the most satisfying experience ever to come from a game disc (blu-ray or otherwise).
