Nah Beaker, I've only played third faction once, and written it into one scenario. But third factions do give the promoter additional leverage and options.
And Raadio... it isn't missing the big picture, it's throwing out additional ideas to broaden a game idea. There are always options for sequels. I mean, a followup game could be something along the lines of the pizza companies deciding to kidnap Ronald and the King and hold for ransom, or at least a percentage of the the burger sales. But a narrow game idea leaves it open to becoming little more than a Big Game instead of a scenario. And I am not saying that the original idea was narrow in scope, I was just trying to add to it a little, throw out some other options.
In short, what it comes down to is if you want a particular game, then write and submit it to Rick and the production staff. Putting it on the boards is a great thing to do, but it also opens your idea up to others ideas and comments.
Just my thoughts on the matter.
