Check this great star wars mod for C&C Generals, "Star Wars: Imperial Assault".
The screenshots are really impressive and recently there's also an amazing teaser avable for download.
The public BETA is going to be released soon, but the guys need support, as they stated in the homepage.
Take a look at it, and if you can support the mod, expecially if you have modding experience! ;)
