Look what I crapped out using the Spore spaceship creator!
I could make the general shape, but not any of the lil' details, so I just gave up and slapped some massive weapons on to make it strike fear into any Spode worshipping scum bags.
i have made all kinds of sweet awesome ships in Galactic civilizations II: Dread lords. perhaps the most awesome fully modifiable space RTS game. i love the ship editor in it.
