No, like I mention in the map thread, the planets are all done in Photoshop, simply by using the the Sphererize filter and some shading on a whole heck of textures that I get from different places. Some I've done myself, some are borrowed with permission from other people from the guild and some are... from the net.
As for the "facts", well I'm not that interested in listing arbitrary data for every planet, so if a certain characteristic, like atmospheric composition, has an effect on the planets inhabitant, I will explain that, but in prose, not in cookie-cutter templates. Now, keeping things coherent, that's the real challenge.
