My favorite game is Wolfenstien 3D. Most people think it is stipid and the graphics are old. Well the gaphics are old. But you can find newer versions. The game was created in 1992 by ID software, the ones who created Quake,doom and other cool games. In Wolfenstien you basicaly kill nazis, search for tresure, secret levels, guns, and beat the game
Wolf 3d has a sequel called Spear of destiny. Another cool game is Blake Stone. It uses the Wolf 3d format.
