There probably is a system that generates approximate values for the ships, but sometimes a ship is more valuable than the sum of its parts.
This.
For once, we'll come clean about our points values (!). To begin with, we simply took the FC points cost of a ship and added 25%.
This was then adjusted during playtesting to suit the differences between CTA and FC. What has been very scary for me (as a designer) is how _few_ ships were modified in any substantial way. Maybe scary is the wrong word - perhaps 'comforting' as it showed that while CTA is a very different game, it is reflecting the relative strengths and weaknesses of ships in FC extremely well.
For 90% of the time, the FC points costs (+25%) can be used in CTA. You just need to keep an eye on anything unusual. For example, the Snipe got a little boost in points because while it is exceedingly fragile, in the hands of someone who knows the game it can be decidedly wicked!
