Words cant describe how great this game is!
I was blown away by this game.
Its the perfect combination of gameplay and entertainment. The creativity that went into this game shows, I've never seen such a "Lush" and "vibrant" single player campaign in my life. Looks beautiful, works beautifully, and surpasses all expectations. The cutscenes are long, but it would be a mistake to skip them, for they are more entertaining then many hollywood movies. Konami really out did themselves this time. If you wanted to nitpick this perfect game, you could put it in the confusing plot. I've beaten the game and downloaded the database and still I'm not sure exactly what was going on. But that can easily be overlooked.
If you own a PS3 make no mistake and buy this game NOW. Even if you haven't played any other MGS game this will surely take your breath away.
