I'm re-opening this, so that all you people can have fun with your shiny new ships.
Some rules, so you don't turn it into a piece of crap...
1) In your post, you can't actually kill anyone.
Grievous bodily harm perhaps, but you can't take somebody out of it.
2) No super ships which 0wn everybody. Same principle as above, it becomes one-sided and, well, gay.
3) Make it funny.
