Sadly, MGS4 is too much...
Wait, i give this "opus" 9.0 out of 10, wich is awesome. But MSG1, 2 and 3 got, in my heart, better reviews for a lot of reasons.
First, the story is complicated the way we like it. However, theres too much story resolving here. Like if MGS franchise was on the verge of extinction, the plot turn around every foe, person, camarade we met in all the previous titles.
All our questions are answered. No magic remains. Nothing to build around. No more mistery.
Second, there is no codec this time. That is very bad, because that was my favorite part of all those back MGS.
However and despite the fact that MGS4 was build with the intention to give the fans "all they have deserved", we still talk about a formidable game.
Just add a little more unanswered questions, PS3 trophies, codecs, and we will have the best MGS ever.
