I remember when I built the Star Destroyer for Block Wars in basically 1 night. I was listening to some PRETTY weird music, and was in a total trance. I'm surprised it actually turned out really well.
edit: also i never played the demo because i tried it out with this stuffty pirated beta version thing which actually let you play online with people who also pirated it. Luckily it sucked just enough to make my friends and i end up buying the game.
and no, it doesn't work any more, and i don't even know if it still even exists.
