I replaced (almost) every NPC in the game with Doc Mitchell. NPCs not included in this would be what the game considers “creatures“ such as robots, super mutants, ghouls, etc... I am not planning to release this as a mod considering that this has a fair amount of issues with it and I probably won't dedicate myself to fixing them. The base game has around 53,000 voice files that I converted and only about half of them sound good.
