All other things being equal, which affects a person more: a book or a movie?
Voice protagonist will suck for quest mods in FO4; every time you run into an unvoiced bit, it will take you out of the game because of its stark contrast with the rest of the world/illusion.
And, at the risk of repeating what's been stated in hundreds of forums ever since the inception of voice acting in games: lack of a protagonist's voice leads to more investment in that character. All other things being equal, which affects a person more: a book or a movie?
Ummm, turn the voices off in options and just read the subtitles if it bothers you. Since this is still the creation engine, we could have Fluent voice all of the main character's lines
The tricky part about voicing the main character in this kind of game is that some players may not like the voice, if it isn't absolute first class, or just for taste reasons. Like, the guy who voices the new Deus Ex games, personally I can't stand his voice, so that is one major reason the games don't appeal to me.
I agree about the voice actor who does Geralt in Witcher 3 though, he is phenomenal.
