Well first, I'd be willing to drive but unfortunately I don't care for 4e, but I do love Ravenloft
What do you, as players or DM's, like or dislike about campaign settings?
As a DM I like campaign settings because the world is fleshed out and you don't have a lot of inconsistencies that crop up with last minute details.
As a player it doesn't matter one way or another unless it's a published setting that I'd be familiar with and had certain things I liked about it. If it's a unpublished setting, than it's a ll new and exciting.
What would you, as players or DM's, like to see in a campaign setting?
A world full of climate and terrain changes for versatility in communities, races, and civilizations. Religious disorder with many gods, similar to Earth I guess Good evil organizations, most of the time in D&D, Evil is so unorganized and falls in upon itself ... we need intelligent evil for a change
