GameScroll

GameScroll is a system for playing and writing interactive fiction like Choose Your Own Adventure(TM) or Fighting Fantasy(TM) gamebooks... But instead of flipping pages, GameScroll runs them as an impartial gamemaster!

Adventures can remember where you've been and what you've done, unlike web-based "choose your own adventure" games! Authoring system as simple as writing a web page!
