Just for fun: Although it has been years since I've done any RPG-ing, I do still maintain a copy of the latest version of Campaign Cartographer, just because I love maps. Using the tools/instructions from an installment of their "Cartographer's Annual", I threw together this map of Terry Pratchett's Discworld, in a style inspired by the 16th century maps of Gerard Mercator (click for full-size):
Note, if you're familiar with the official published Discworld Mapp, you'll see a few differences, based on the ostensible reason that the map was created by a cartographer in Ankh-Morpork. Therefore, Ankh-Morpork is near the top of the map (rather than toward the bottom, as in the official map), and the further away from Ankh-Morpork and the Circle Sea region you get, the less detailed and more inaccurate the map becomes. So most of the Circle Sea area is pretty close to "reality", other parts of the continent are fairly accurate (but not very detailed), the Counterweight Continent is pretty much right, but with a few errors, and the least-explored areas - XXXX and the Lost Continent of Ku - are wildly inaccurate.
Here's also a close-up of the Circle Sea region:
