If you’ve already taken a look at the Supreme Commander map editor, you’re probably a little confused. At first glance it doesn’t seem like there is a whole lot there. You’ve also probably noticed that there isn’t quite as much polish as Supreme Commander itself. This is because the tool was first built for internal use. Don’t let that get you down! This is the same editor that GPG uses at their studio. We are very lucky to have access to it. Everything you need to create rich maps like the ones that shipped with the game can be found in the editor, once you get used to it.
A word of caution: a good map takes many, many hours to complete. A lot more goes into maps than throwing up a heightmap and slapping down some textures. Doing those things is easy enough, but doing them in an interesting and gameplay promoting way is very difficult. If you have the patience, however, playing on a map you designed yourself can be a rewarding experience.
