Morrowind is one of the truly amazing RPGs among videogames. Over the last 20 years there probably have been hundreds of fantasy videogames, but Morrowind has always been in a category of its own. Even when you look at fantasy works in other mediums, it’s still something very unusual and quite unique. Most recently Skyrim has had a huge impact as the last game of the Elder Scrolls series, but as pretty as the world of that game is, it’s still mostly pretty ordinary European-style medieval fantasy, with Vikings driving out the Roman Empire from their land and some dragons and elves for good measure. Nothing we havn’t seen a thousand times before. But Morrowind, even being set on the same planet and right next door, is a place very much unlike anything else in fantasy. The most similar setting I can think of would be the AD&D world Dark Sun, and you might also consider the venerable common ancestor of all heroic fantasy and space opera Barsoom from A Princess of Mars.
Very obviously on first glance is that Morrowind and these other settings have very unique landscapes and wildlives, as I had mentioned two weeks back. The plants look different and there are many common animals that are not seen as monsters but are completely unlike any animal we have on earth. (Or at least in Europe and North America.) And even more, there is also a noticable absence of almost any animals we are familiar with. But that is only on the very surface and only affects how the world looks. While the visuals in Morrowind look great, it is not all there is to it and this element is mostly irrelevant for stories or campaign settings. Strange looking animals and plants don’t make a difference by themselves in regards to how the world and the people in it tick.
I’ve been discussing this topic with other people over the last weeks and it resulted in quite a number of very great thoughts, realizations, and discoveries about what you can do to create a world that feels similar to Morrowind without being a direct copy of it. And even if that’s not your intention, any single one of these should be useful as a starting point to making your work more unique and different from the standard medieval European fantasy.
