Fallout 4 seems to literally give voice to the main player-character, confirming our suspicions from last week's teaser trailer.
In Bethesda's E3 press conference they showed gameplay clips during which the character engaged in various conversations. What is special is that the male character spoke out loud throughout the various samples of dialogue. This makes it the first Fallout game to feature voice over for the main character.
The publisher also confirmed that you can play as either a woman or a man, so that means probably quite a lot of recorded dialogue. Basically all the conversations have to be recorded at least twice, and we still don't yet know how many different voice options there will be.
