I created a role playing system with not too much of a Fantasy setting about 15 years ago. It played well, but when it started to reach the 4th revision, this 4th revision I had put weeks of work in was lost in a hard disk crash. (I still have the 3rd revision.)
Armageddon is a setting in the Unisystem published by Eden Studios. I love the setting, but I hate the Unisystem for being an unbalanced luck-dependent and not storyteller-led system.
As my playing group looks for something new, I decided to rewrite my old system for the Armageddon setting. As it begins to be more mature, I wonder if I could ever publish it with the exact setting of C. J. Carella's Armageddon, but entirely my own text and system. I tried mailing Eden Studios, but didn't get an answer, as you already expected.
Self-publishing is okay for me, I would also be able to get the dice and the cards needed to accompany a book, but the legal issues make me wonder what I can do.
