I've been wanting to showcase this mod for a long time now. Its still under development, but the models, units, vehicles, etc. are really awesome and all of the tools are there to make some seriously impressive maps and battles on any number of planets in the Star Wars universe.
Most of the content for this mod can only be launched from the editor, but it is pretty simple to create some nice battles, both big and small. Here is a simple Imperial assault on a small rebel held village on Tatooine.
You can download the mod here: http://www.moddb.com/mods/star-wars-gaw-mow (http://www.moddb.com/mods/star-wars-gaw-mow)
Some additional maps and a few missions/campaigns can be found in the steam workshop and on the web, but I've found that several are not compatible with the latest version of the game.
If you have any issues getting set up, post your questions here.
Enjoy!
