I'm sick of people saying that Samus not having a voice before this game made her a silent protagonist.
She talked all the freaking time in Fusion, having internal monologues in every other elevator shaft to heighten the sense of being trapped and alone on a ship with a story that sucked but was still ten times better than Other M, and the text introduction to Super Metroid, told in first person by Samus, is still one of the best I've ever seen, setting the mood for the game perfectly.
Just cause she's got a voice now doesn't mean she was silent before.
(I'm not counting the Prime games cause Sakomoto has already said they're non-canon and don't reflect the personality of Samus at all, which is BS but whatever it's his character)
