MGS4 is just unbelievable. It’s the first game I have ever played through twice. First time, I just went in guns a blazing, but on the second run I managed to do a full 0 alert and 0 kill run. This game has just blown everything out of the water in terms of what I thought was a great game. I might even play it again. The story and gameplay are just fantastic. This game alone has made the PS3 worth purchasing.
