As Pmiller said, my two games have open slots. The first, Black Company, is based off of Pmiller's pathfinder conversion, and is a fantasy homebrew setting. It is set against a back drop of war, where players are convicted felons given second chances in a special army company.
The second game, is a Star Wars what-if scenario. Basically, the Jedi Order controls the Empire and the Sith lead the rebellion. Players are rebel recruits that fight for the fate of the galaxy. The conversion uses SAGA as a base, but is similar to the other conversions. Here is the doc for it: https://docs.google.com/document/d/1_0J ... aJboA/edit
One thing about these rules lite system is that once you understand it, it is very flexible in terms of character building. It is a classless system, so you can really branch out with unique characters.
