Actually, it is possible to improve the graphics in the demo with new ones downloaded from BC files, it just takes a bit of effort and patience and time. I could tell you how to do it, but its a difficult process and it may just be wiser to buy the full version. There's really a lot more you can do with that, either way. But if you want to know how to stick new ships into the demo, just let me know and I'll lend you a hand.
