The D&D campaign I am about to run is based on a huge planet (many times the size of earth) where some of the continents are so far apart that they live in completely different eras of technology, cultures vary wildly and the environments are drastically different from one another. The continent the campaign starts in and serves as the PC’s home is in the middle (Although far away from) a number of other continents, who other the last few thousand years it has come into contact with. It is about to leave the traditional “Medieval fantasy” era and is developing into various different kinds of technology (SteamPunk, Magitek, Digital, Industrial to name a few) and the continents around it represent various different setting types (Steampunk, Western, Gothic Horror, Modern day, Futuristic, Oriental… the list goes on.) Basically, the main continent is having all various kinds of cultures and technologies thrown into it and blending together.
D&D is most often seen as pure, traditional fantasy and some think that is all it should ever be.
However, how has your experience in D&D been when you take a campaign that takes place in a setting or genre that is not supported by D&D (Such as one of the ones above?) or has blended many different genres types together?
Did this work well? Or was some kind of unrecognizable mess?
I’d like to hear your opinions on this.
