I am a huge fan of Bethesda's Fallout games so far, but why on Earth would they give the main character a voice!? Not only that, but from the gameplay they showed off at E3, they dumb down the dialogue options to only 4 mapped button options. Even worse is that those options hardly tell you anything about what the character will say. This system is the same system I've seen in so many other games that I absolutely hate. You choose a vague option from a small list, and the character does whatever with that small hint of dialogue you read. You choose the "not interested" option, and next thing you know your character is killing the guy you're talking to.
Now I know Bethesda has great voice acting and that the voice actors did a lot of work to make this work; but even so, the main protagonist of a role playing game shouldn't be voice acted. I want to immerse myself in the world, like I did with Bethesda games that came before it. I don't want to assume the role of someone else; I want to be me. Having the main character talk breaks that immersion and limits my options when playing. I should at least know what my character is going to say ahead of time; but from the gameplay we've seen, we won't know.
One of the greatest things about playing Fallout 3 was reading out the dialogue option in my own voice before choosing it, and then to have the NPC's respond to it as though I was the one talking. I could play the game a hundred times over and always feel invested in the game because I got so immersed pretending I was there. The biggest problem now is I won't be able to do that.
Don't get me wrong, everything else in the game looks amazing, but what's the point if I can't get invested in it. I know some people are really excited about the main character talking, but I know plenty of other people who are concerned about this change as well. I really hope there will be an option to play the game classic style with all the dialogue text in your options and no voiced protagonist. If not, this single decision might just ruin the game I've been waiting for over 7 years for. It will be a serious disappointment if that happens.
