Ever wanted to travel through time, become a master at martial arts, eat soup and own a primate, a castle and a starship? Then this is your game! Wiki-Based-RPG is an open source, text based game, with somewhat experimental gameplay. The server writes a story - based on key words which the game gets from Wikipedia (or any other wiki, if you modify the code a little). Between every two story sections, the heroes (the players) are allowed to reply by saying something, doing something or using something from their inventory. No two stories are alike, but all stories are guaranteed to be crazy! At the end, you can export the story directly to .html and show your friends, post it, or send them to me so I can post them here!
Good and simple idea. Great to play with old and new friends.
