Hopefully you guys enjoy the read!
I'm mostly a player of the Unreal universe and only tried UnrealEd out many years ago. I was actually surprised to find out that UnrealEd was written by Visual Basic (Windows complained that I missed some related ocx files). But of course you guys probably agree that UnrealEd 2 is much better than UnrealEd 1.
Wish I could see the source code though. It would be interesting and sometimes essential to write one's own map editor.
