EpicQuirk is a dynamic multiple choice story game. You can either play on other peoples one-shot stories or make your own (to make your own story you'll need to register an account). The game itself will select a random outcome, weighing the pregiven probability of each outcome.
Of course that above won't make much sense to you all. Just try it out. It is in BETA, so I'd love suggestions and ideas on how to improve that game.
