I don't think that trying to get people to play a succession game of dwarf fortress, when most of them probably have never even heard of the game is a good idea.
It has a very steep learning curve. Not to say that it isn't a good game. A general discussion thread would probably be more wise until people gain an interest.

Boatmurdered is one of the more interesting succession threads.
