Viridian Dreams is the website of Viridian/ S'Tarkan, author of Team 8 and Harry Potter and the Nightmares of Futures Past, and long story short, his forum is full of writers, or at the very least people with too much time on their hands. One of these good/bored writers started Ninja Quest, a play by post game, and the forum hasn't looked back. There are a number of quite good, currently running quests (Play-By-Post Games with collectively controlled protagonists), several dropped quests and Let's Plays and a complete Let's Play. There be spoilers.
