Polygon:

After 10 minutes of working with Hale, Ernst and Pobst noticeably relax. It’s working. The new character, voiced by the veteran Hale, sounds better than they’d hoped. Stitched together after the fact with the voices recorded by the other actors, it will somehow feel perfectly in place. Even though Hale had never heard those voices, and hadn’t read the script until today.

Ernst and Pobst celebrate with pastries and warm smiles, while Hale continues to rocket through the script, laying down lines, adding life to the game that’s still being made hundreds of miles away, in a completely different state.

This is game development.

I don’t know if voice work can make or break a game but I definitely notice it and it can affect my enjoyment of the play.
