When it comes to dialogue, accents are the first thing most folks immediately think of but, as the Crack guy did mention, a voiced protagonist in an RPG is limiting in so many ways. What if I want to envision a character who is a slightly-annoying fast talker a la Tarantino? Or a quiet type who utters their lines of dialogue in short, clipped sentences? Well I'm shit out of luck because I'm stuck with whatever inflection the voice actor chose to read their lines with. Imagination goes right out the window, and this is a big no-no in an RPG that's supposed to allow for freedom of character creation and customization. A voiced PC in a roleplaying game is a major sticking point for me. Frankly, it is yet another needless limitation Bethesda seems intent on forcing upon the player, in addition to their penchant for fleshed-out backstories and watered down RP mechanics.
