The Best yet!!
Gameplay: The gameplay is just about perfect. I love the fact the it adds a little bit of reality in the fact that you have to eat to survive. The only thing that could have been done better is the camera (Good thing they fixed it with Substance).
Graphics: The graphics are the best. From the shining water to the shadows from the trees above. The cut scenes are also rendered beautifully!
Sound: Awesome! From footsteps to birds chirping to the snapping of a enemy's neck. You can hear everything. The soundtrack is great too.
Value: Best value of any Metal Gear game!!! Buy it now.
Overall: If your a fan of Metal Gear, you need to own this game. The replay value alone is worth it.
