My biggest beef for most silent protags, is there's never a REASON for them to be silent. Did they commit some crime? Are they just a Mute? Were they an accomplice to some murder? Was there an evil dark lord who cursed them so they can't reveal the knowledge of how to defeat them to others?
No, no, No and no, they are usually silent...just because. Meaning I have no reason to care about why they are silent. And even less of a reason to care about them.
Like there are a few cases where dialogue options do come up. But so often they have little to no characterization. And a common problem is those choices have no agency in the story as others have said.
Put this in your sig if you are against having another fire fighting starter. Actually don't, gamefreak doesn't care about gamefaqs signatures.
