I think Rob and I are in the same situation. We have settings that are complete but are only partially revealed. On the one hand it creates a bit of mystery but it also limits what the GM can do with a game and not feel like they were overridden later in the story. It also makes material that is revealed later potentially useless to the GM if they took the world in a different direction.
So my question is, is it better for a GM to have all the background revealed, or is it better for the mystery (and simpler assimilation) to limit the story and just hint at the larger background?
I want to eventually get to my larger background by making a second game in the series but it's a slow process. So my questions are. . .
Are you happier as a GM knowing less or knowing more?
Is it harder to pick up a setting that is very deep even if you don't need to know what's going on in the background?
Is it worth holding back information so the players don't know and have to speculate?
What is the best method of getting information to a GM and not players? (GM section?)
