I recently made an adventure in the text adventure/GET LAMP vein, following the lead of Jared Sorensen's Parsely Games
Check it out: Death Dungeon!
It turns out that it is super simple and fun to make a Parsely adventure. It only took me an afternoon or so to figure out the rooms and puzzles, and only another day or so to make the PDF file.
The thing I like best about the PDF is the form factor. It was initially designed to be printed on 11 by 17 paper, but if you scale it to print on a normal 8 1/2 by 11 sheet and trim the top and bottom edges, you get a nice little pamphlet that fits in your wallet. Take your dungeon crawl wherever you go, and entertain your nerd friends while waiting for the movie to start or whatever.
I also think that there are interesting and complex relationships between Parsely games and the Old School Renaissance, but that might be fodder for a different thread.
