Edge: Ever since I can remember, I have loved using level editors. I got my start before I was even a teenager building Lode Runner levels on the VIC-20, by my mid-20s I was making levels in UnrealEd, and my first game industry job was as a level designer. The game level editor was at least as important to my personal creative development as was the word processor. I believe a good level editor can be as engaging and entertaining as a game itself and - when combined with a great game - has the potential to create a positive feedback loop between playing and creating. This is important if you believe - as I do - that playing and creating are fundamentally the same thing.
