I've seen it brought up a time or two but I really do think the page needs to be trimmed up a little bit.
By saying this I mean games like Fallout, and Elder Scrolls cannot be on this list much like any character in a text based game. Just because you don't hear your character doesn't mean nobody does.
Sorry to bring it up again, but I saw the last time this was really discussed was like 3 years ago.
Also, the character from the original Saints Row isn't a "silent" protagonist, he speaks like 3 times
