Do you have framework for some game mechanic? Or perhaps awesome drama arc written for film? Maybe you need fresh new ideas for everything else? Thats what i could do. I am always bursting full of ideas, and i love nothing more than filling out worlds with my own visions and designs of what some distant / foreign world might look and behave like. What do the people of that world look like? What sort of culture they might have? All these and much more is what i can fill in. I get all of my inspiration and ideas for this, from Aldan (see its individual link in top menu).
