He should also have a backstory, these games are getting progressively bad with each release
and I think the fact that you can't relate to the character or empathize with them has a lot to do with it.
Gamefreak, get off your asses and make a real narrative for once in a main game. Put effort into these games like you do the mystery dungeon series when you make a story. If main characters can talk there, why can't they here?
No. The MC doesn't need to talk. Though I would like more yes, and no segments, and be able to shape the story how I wish. The thing about having a silent protagonist is that his/her personality can be however I wish.
