Guys, I was talking about SKILL. Not resolve, courage, wisdom, or anything else. The fact of the matter is, Raiden beat an immortal dancing vampire thrice, defeated 25 RAYs, defeated Solidus (who is arguably as much of a soldier as Snake, and is a great politician too
) and could knock out Arsenal Tengus while naked.
Snake is the more experienced veteran, but you have to remember that his accelerated aging is doing nothing but hurting him. Whether or not you agree that Raiden is as good as snake, by the end of MGS2, he has nowhere to go but up, while Snake has nowhere to go but down.
Kojima wanted the cutscenes redone like that because he thought they conveyed the idea of Snake as an ultimate soldier much better than in MGS1. You might still prefer MGS1, but Twin Snake's is part of Kojima's vision of the series.
