What YOU fail to notice is that agnickolov is still correct. Wolfenstein 3D was developed by id software. The article says it was DEVELOPED by 3D Realms, and it most certainly wasn't. Developed is not the same thing as published or distributed.@agnickolov
What you failed to notice is... the Wolfenstein game was distributed by Apogee Software (DOS version) which is AKA 3D Realms.
