I also bought this game for the editor. The game looked awesome but when I saw there was an editor I took the plunge.

I spent a bunch of time searching the forums to figure out how to download and setup the editor. Watched the tutorial videos and practiced by building a small prison scene.
There must have been one or more updates since the tutorial videos because the editor contains bugs which are not addressed in the videos. Also the video leaves several pieces of required code out but somehow it works fine for the instructor. Again I found the answer on the forums. I know the videos are stale after the first update but please at least provide release notes for the editor.

I've spent about two months learning how to use the editor. The most frustrating part is how unpredictable it is. I've completely rewritten systems in my mod to fix errors, only to have the editor begin crashing upon loading the mod. It doesn't crash when I reload the level, the story, or switch mods by opening a blank and then opening my work. Not to mention the terrain bug. If I wasn't so hard headed I would have quit by now and moved onto a different game. The problem is the dang game is so good..

I also wonder how in the world they made DOS with this editor...
