I have to disagree on the issue of a voiced protagonist in Fallout 4. I have not completed the main story yet, but so far all of my story engagements have been far more effective than in previous Bethesda entries. I should add that I was very skeptical about the whole VO thing when it was announced. I remember an article from Forbes shortly after the trailer came out claiming a voiced protagonist is an absolute necessity for a good game, and that really got my hackles up. However, it seems to me that this argument falls apart on two fronts.
One: The tool kit hasn't even come out yet, and there are already at least two serious "No Voice" mods available at NexusMods (and one that adds fart noises in place of dialogue), one of which came out on the 11th of November. Unless I missed a follow up from Bethesda, they announced that modding will be possible on all platforms, not just PC this time around. So, while you may have to wait a bit, there will definitely be some well made mods that remove the main character's voice, and I'm sure they will also fix conversation camera angles to correct for the lack of a voiced dialogue if they don't already. To possibly abuse an axiom, it is better to have a voice and not need it (for those that prefer a silent protagonist), than to want a voice and not have it (for those that prefer a voiced character).
The programming solution: Have more than one VO per gender, and/or give players the option to toggle it. I agree with the immediate counter argument that devs shouldn't rely on modders to fix their games.
Two: It seems like Shamus shot this one down himself when he brought up Skyrim. Poor conversational logic is an issue for Bethesda and non-Bethesda games, whether there's a PC VO or not. There are plenty of examples of NPCs reacting poorly to lines delivered by the silent protagonist. The situation that seems omnipresent in cRPGs is the missing "Lie" option for every dialogue choice, and the lack of follow up from a companion that disliked the option you picked earlier. "Oh, you were lying to the bad guy when you agreed to help him? I was totally wrong when I yelled at you back in camp." If someone knows of a cRPG that this type of thing would happen in, please let me know, because I haven't come across one yet, but I'm aware that my scope is limited.
The same can be said for unavoidably stupid situations that the player is placed in because the conversation can only end in one way. That is a programming issue, sure, but certainly every cRPG that I've ever played has at least one moment like this. The only way to avoid it is to not play cRPG's at all, and stick to pen and paper/tabletop gaming, where your programmer is directly involved with your gaming experience. Even then, you still have to find a GM/DM that you like.
The programming solution: Stick to game devs you like, because this can't really be fixed without some drastic leaps in video game technology. Also, support the devs/modders that you think are capable of making these leaps happen; I know I do.
TL
R - Mods can/will fix the VO if it's an issue for you, a VO doesn't make/break bad conversation programming, and these problems exist in all past and current cRPGs.
