i finally made my first playable doom 3 map. it's a square box. yay! a lot more complicated than i'm used to with other builders though. i'll see how it progresses. and nice, all you need is doom 3 to build maps. to make textures etc, you will need a photoediting program, and maybe more, since doom 3 uses advanced bumpmapping textures. i'm not sure how to edit those.
