The world has come a long way since Wolfenstein 3D, and even longer since Castle Wolfenstein in 1981. John Romero, one of the founding members of id Software, who developed Wolfenstein 3D back in 1992, doesn't work on the series any more, but he still keeps an eye on it, and thinks MachineGames's take on the series, with Wolfenstein: The New Order and Wolfenstein II: The New Colossus, is the best it has ever been. 

On a similar note, MachineGames worked out that if they wanted a player to shoot something, the best way to ensure they did was to put a Nazi in front of it.
