Never underestimate the, uh, dedication of a Battlestar Galactica fan. A fellow who calls himself Ibanez is working on the Battlestar Galactica Tactical Mod, which lets players take on the role of the commander of the Galactica during an attack by a Cylon base star. As he enthusiastically describes it:

We will be the commander of Galactica this time. Not a noob viper nugget pilot. You can actually feel that you are watching a battle from the movie with increased AI aiming, AI thinking, detailed models, commanding freedom and with your own strategy to survive and protect the human race!

That may not sound so far-fetched until you realize what game he's working from. This mod is based on Mount & Blade, a medieval combat game. Just to give you some idea the lengths to which Ibanez has gone, here's Mount & Blade before the mod:

And here it is after the mod:
