Getting ready to start up a new D&D campaign and I'm running into a problem that I imagine a lot of DM's run in to. And that is that I have no idea which setting I want to use. My first campaign was a custom setting and while that was fine as the world was pretty much 100% malleable, it becomes a lot of work, and PAPERwork to contain everything pertinent to the campaign. How about you folks, any of you Dungeons and Dragons players have a preferred campaign setting? If so, why?
