Cantr II

A webbased and textbased multi-player simulation where you can explore the world, get into politics, get rich or become a criminal. You can start several characters. It is not like most MUDs, as there are no races or skills or quests, but you simply play a human character in a world comparable to ours, in which you can help develop its society. It's all about 'reinventing' politics, economics and other societal institutions. Just have a look at the website for a more detailed explanation.
