Re: Creating a "campaign doc" for players in a new/original campaign setting...feedba
I'd be sure to list all the major villains/organizations you plan to use (along with a short, short description for those unfamiliar with Champions), as well as those you absolutely will not use (just so they don't base their whole character around being hunted by them or something...obviously this one is for those who ARE familiar with Champions). This should help them build characters who are more closely tied into your planned story arc. Just keep a sharp eye out for metagamed PCs optimized to take out your main bad guy.
As far as background content, I'd start with very general strokes and work into the details later. That way, if somebody is absolutely riveted by your material, he can sit on the edge of his seat all the way to the end, but the guy whose eyes glaze over before the bottom of the first page will not be totally lost. If you have to, do a brief overview of less than a page, do a somewhat more detailed summary of maybe two pages tops, and then do the full Monty as its own document.
