Stargate Game mods - List your favorite mods for your favorite games!

Over the years I've been surprised by the number of mods created by fans of the show while waiting for an official IP game (Timekeepers does exist now, but is a very niche game). I thought this would be a good place to highlight some of those and will probably turn it into a side-bar spoiler.

What are some of your favorite mods you've ran across? I will populate and edit a list with the responses. If you wish to rate or describe the mod I will include that and your username as well. Links will be helpful but not necessary.
