Freelancer - Liberty Cruiser
I made a bunch of spaceships (and other stuff) for the game Freelancer. It was a lot of fun! I really loved the look and feel of all the concept art, and found it very inspirational. The game was in production for so long I was sure it was never going to actually be released, but it did in fact ship and turned out to be pretty good, despite some hiccups along the way, production-wise.
