World-building is a very rewarding thing and can be a great part of any D&D campaign, but honestly, making world-building a default part of the rules??? That is utter madness. DMs already have so much to do. Now, I am not opposed to a section in the DMG (perhaps a world-building "module" if you will) that helps DMs build their own world. Such tools are invaluable to DMs who want to do just that. But not every DM wants to build his own world. I myself have run the large majority of my campaigns in either Greyhawk or Eberron? Why? Because I find a world with an intriguing background and history and from there it is that much less work to do. I actually have my own fantasy world. But to be honest, it does not begin to compete with the wealth of information that is available on these two published settings. And quite frankly, writing so much detail about my own world would probably be mostly lost on my players. But I can still enjoy a campaign setting-specific book even if I only use a part of it.
