Awesome, especially the space station. It looks like mine only about five times bigger.
As for the rail gun frigate's rules, I would say that the rail gun is a fixed forward weapon with unlimited range, and that the number of damage D6's it has varies depending on the ship's CP allotment, since a larger ship can carry a heavier rail gun.
Just one random act of violence can brighten your day. Especially if it involves explosives.
