Kinda wanted to add speech bubbles: "Punk." and "Grandpa" to the characters but didnt get around to it. Well, I suppose you can tell who says what...
For the record, my money is on Old man Snake. >
in this fight, thats snakes advantage. in cinematics, all kinds of things happen that you cant do in gameplay. therefore, sam fisher is bound to the few things he can do in-game, whereas for snake, a cutscene starts where he takes sam fisher apart.
also, fisher isnt a big boss clone. hes got no chance. i bet he doesnt even lift.
