I'm currently developing a game called Deus on the RPGLAb site. The game is finished to a level were playtesting is able.
I'm intenting to a play be email playtest starting on the 16th of April.
The above link is to the game as a whole, with details of how to join under the Deus Collaborative Game section.
I have to say that I'm going to be away for two weeks so don't expect reply to email submissions. I would, however, ask you to make deities and email them to me if you are interested.
If you have any questions there are several members of that site who have followed the games process (such as Decreased and ChainsawAardvark) who might be able to help, but don't expect them to be definitive.
I'm looking for a minimum of three more players, but more are welcome!
