1. An RPG based on being a "Gothic Fiction" archetypal type monster. Werewolves, Vampires, Ghosts, Skeletons, Mummies, Reanimated Corpse (Frankenstein), and stuff like that. 2. An RPG of something you've wanted to make, but publishers didn't buy off on it. 3. An RPG based on time traveling. 4. I have another idea, but I think it would bore other gamers to tears. It also would require a Star Wars license.
