Todd Howard recently revealed in an interview with the Telegraph that both the male and female protagonist in Fallout 4 read over 13,000 lines of dialogue for the game.

Fallout 4 marks the first time in the series where the protagonists will have speaking roles. In order to make sure players didn’t lose that sense of choice, Howard put his voice actors to work on this project.

“We had the same worry as everyone else. A lot of games have voiced characters, but what they don’t want to give up is all the dialogue options. So for us a lot of it was logistical. The voice actors have been recording for 2 years, they’ve each done over 13,000 lines of dialogue. So to be able to do that makes the difference; you still have choice.”

And even though many lines were repeated between the scripts, you can still get completely different scenes depending on if you’re playing as a man or a woman because each actor interpreted the script differently Howard continued.

“We were lucky to find two great voice actors and it’s interesting because she may read things or act things differently than he does. So scenes play out differently depending on whether you are playing the game as male or female.”

The voice actors who had to work those grueling hours delivering all those lines are Brian T. Delaney and Courtney Taylor. Brian is also playing Roland in Halo 5 and Mighty No. 5 in Mighty No. 9 this year. Courtney is probably best known for her work as Jack in Mass Effect 2 and 3 and Amanda Holliday in Destiny.

Fallout 4 will be out on November 10 for Xbox One, PS4, and PC.
