I am fine with voice acting for the most part. I only start to dislike it when they add a voice to my custom character in an RPG where I am supposed to be roleplaying.

Fallout 4 is the best example of how this can ruin my experience. I like the game. Fun gameplay. Fun base building. Interesting world and characters. But when I go to make MY character... I can't.

Because the voice they gave Fallout 4's protagonist does not match what my character would sound like at all. Not just in voice but in tone and the emotional range they give to different reactions. It does not matter if my character is a scrawny redheaded scientist who is obsessed with aliens and believes they caused the Great War. He's going to sound and act like an ex-soldier looking for his son.

Not to mention how much expensive voice work reduces the amount of dialogue the game can afford. Fallout 4 has four responses to basically everything. Yes, No, Sarcastic Yes, and Sarcastic No. I couldn't do things like ask about a woman's life story and diagnose her mental trauma with a Medicine skill check like I could in New Vegas. The dialogue branches were short and concise to limit how much the voice actor had to say which meant I very rarely could handle conversations the way MY character would handle them.

I've tried to play Fallout 4 several times now but keep losing interest before I ever meet the Institute because no matter what angle I come at it from my character that I make sounds and behaves exactly like all my other attempts, and NONE of them have been the character I sat down and designed for the game.
