Doom port genealogy. There are a lot of user made extensions for the doom engine. After Id Software made the games source code GNU, the doom community gave the engine wings. Now it's capable to use 3d acceleration, mouse freelook and tre room-over-room effect. The true room over room ends the distortion of the textures when the use is looking up or down. Interesting and very long article about the doom family.
