Quite honestly, I am sceptical about having a voiced character. It takes away that feeling of the character 'being' me, if you get what I mean. It's as if the character is talking for me, and I'm just telling him what to say as opposed to me, the player, actually reading the lines in my head. If it's optional, then I really don't mind. It I had a choice, I'd have no voice though.
But what he means is that each Fallout character has had their history set in stone - the player (you) cannot alter it. In Fallout 1, you were sent out of your vault to retrieve a water chip. You were already a vault resident, already knew people in the vault, and were rushing to save them. In Fallout 2, you were already part of a village and, again, had people relying on you to save the village for its imminent destruction by retrieving a GECK. In Fallout 3, you were ALREADY part (again!) of a vault and had to leave to find your dad. Your history was all pre-determined. And finally, in Fallout: New Vegas, you were already a courier who had already walked a long, long distance (as evidenced in Lonesome Road). You had even unknowingly detonated a set of nukes.
Now, one way to combat this, would be to introduce the player as either a ghoul, meaning he lived before the war, an android built for a specific purpose, or a human placed in cryogenic stasis.
1. Ghoul - If you were a ghoul (unlikely), you could select your tag skills and traits based off the occupation you had BEFORE the Great War.
2. Android - If you're an android, you could, again, select your tag skills based off the purpose for your design. If you selected Lockpick, Science and Pickpocket, your story could include that you were developed as an android to infiltrate certain places. If you selected Big Guns, Energy Weapons and Explosives, your backstory could include you being developed as an android to protect the Institute, (or where ever they develop androids).
3. This option would work the same as being a Ghoul, with the exception of being a human.
What I am trying to say is that it would be so awesome if the player could make their own history, give themselves a reason as to why they're where they are. Why are they in Boston? Why are they wearing a Vault 111 jumpsuit? And so on...
But I suspect they have already set a story for the protagonist, and it appears as if he came from a Vault. This rules out my options 1 and 2 but, however, leaves option 3 (human placed in cryogenic storage) open.
