Query: Doom

Doom is a very good first person shooter and next to wolf3D it is the greatest game ever made. Wolf3D is the grand daddy of morden 3D games but it was Doom which made the world sit and take notice. Without Doom there would be no multiplayer tournaments, I think doom is the game which started the multiplayer games with co-operative and deathmatch gameplay. You play a soldier sent to another planet to destroy the aliens and save the world, The gameplay is very good and the controls are very easy to use. The length of all the games are very good. Finally i think an OpenGL patch for Doom called GLDoom was made by a gamer using the doom source code. I read that on the net a long time ago. They could have included that patch in this edition. If you like doom then get Heretic, Hexen and Wolfenstein3D you will like them too.
