But Wolf3D was the “3D - FPS” which changed the world, and gaming introducing FPS. Carmack glimpsed Ultima in action at a 1990 expo, and saw a new style of game, influencing him in both Wolf3D and then Doom.
Also, ID’s first 3D game, which was not FPS, was Hovertank 3D!!
So all the arguments here revolve around if you are talking “3D” or “FPS”. 3D has been around since the 70’s, however as far as FPS is concerned WOLF 3D takes the title for that.
