The gameplay isn't better, I found no way to put your gun down without firing a shot, because the stupid Gamecube controller sucks. And the over the top cutscenes bring the whole thing down. I'm pretty sure they were meant to be a joke, because Snake isn't actually supposed to be able to surf on a freakin' missile.
