The 'FWE' stands for Fractal World Explorer, which comes with AstroSynthesis. Now that I've found Celestia, FWE is really the only part I use any more. You can do a lot with it with some effort. If you get it, just keep 2 things in mind: The 'Shading Exaggeration' and 'water/wind erosion' settings are very important. Also the order in which you execute processes can have totally different results...like say, you 'water-erode 200,000 years' and THEN decrease the shading exaggeration, the result is totally different than if you do it the other way around.
Anyway, here's an Earth-like terrain.
