More than just the GM mode, though. I would like the ability to create stand-alone playable mods. Think of the old modules for D&D (e.g. Tomb of Horrors). Yeah, you need a DM for those too, but with computers, you don't. They could sell those at $5 a pop (or more) and make a killing, even with the community make their own. Time to bring, as much as possible, the full D&D experience to video gaming.
That's what the toolset allows, hopefully one a bit easier to use.
