Unfortunately, most of the best moments for me are piled into the last two acts of MGS 4.
That being said, every time the Boss would get into hand to hand combat with me in MGS 3 gave me an awesome rush of panic. That, and fighting the thirty Metal Gears at the end of 2 had the words "THIS IS SO AWESOME" running through my head the entire time.
And in MGS 1, when Snake asks, "What happened to the music?" Priceless.
