I have trueSpace 2.1a, 3.2, 4.something and 6.5, also have 7.something but the user interface is flat out horrible and needs either dual monitors or one really enormous/high-res one.
I've had an idea for a BSG ship kicking around for a few years...
Before the 'peace treaty' with the Cylons, the first pair of new and upgraded side pods for the Battlestars, along with the first upgraded engines, had just been completed and were in a spacedock, along with a full complement of an upgraded design of the Viper.
When the Cylons attacked, the people at the spacedock (which was away from any of the 12 Colony worlds due to it's high target value) took one of the pods, turned it around backwards* and mounted a couple of the engines to its nose. Outfitted with old turrets (the new ones had been held up in red tape, thanks to Sire Uri), fuel tanks and various other bits cobbled together, the 'Half-a-Star' was launched.

Its first action was to destroy the other side pod, the spacedock and everything else they couldn't stap on and take with them. Perhaps they were able to drag along a couple extra engines that could be used to upgrade the Galactica and reduce its fuel consumption a bit. (Higher efficiency, more power from newer technology.)
*They still hadn't come up with the concept of a full length, fly through landing deck, relying on gravity fields to catch bad landing attempts. Even if it was fly through, one end would go between the main engines so that wouldn't be useful with the engines running.
