Does anyone here remember
Freelancer? It was a space shoot-em-up with some RPG and trading elements and an absolutely atrocious grasp on the concept of scale, but it was great fun and some of the ship designs were just lovely. Anyway, I've been on-and-off building some tweaked versions of ships from the game with my own little design bits added for flair.

The Z-1100 Pantera light gunship, based on the pirate Bloodhound fighter.

The F-2000A Avenger light multirole interceptor, based on the Liberty Patriot light fighter.

The GD-750 Trailblazer, based on the civilian Starflier (AKA that piece of crap you start with).
All of the ships I've done so far can be found
here, and I'll probably add more as I go.
