I too am sad about the MC not talking, voiceover is what set the tone of the immersion for me.
I also completely disagree whit the fact that a muted MC brings more rp into play since you can read the way you want to... problem is, however you want to read something, the game decides how it is percieved anyway.

At the end, to me, it feels incomplete; it feels the same as if half of the sentences were voiced and the rest not. I hope at the very least that the "premade" characters will have complete voiceover.
