Does anybody here use it? It lets you create your own adventure games like 'King's Quest' or 'Monkey Island'.
You can download the porgram and many games created with it from their website at:

Wish I had more talent, then I may actually make something.
Looks like a nice tool, I'll have to toy around with it. I also suggest checking out Inform 7 if you're interested in developing text adventure games.
