Hello, let me introduce myself I just got Doom3 for my Bday last week and almost finished the original game. I havent used a walkthrough or cheats or any mods yet and I really enjoy the game with just a few minor gripes. I just wish the game was a bit longer. I owned the previous Doom(s) and Q1 and Q2, however I never mapped or did anything but just play the game. Doom3 I intend on turning a new leaf and wish to try to do some mapping and other stuff. Is there a good place to get some good basic knowledge on this as I will need to start off in the 1st grade as I know nothing of this aspect of the game.
