Bearing in mind what I've previously said about the CBF core rules, I decided to enlarge my options with this add-on & see if this improved my perception of the basic games limitations. Unfortunately, no ...
As with basic CBF it's a good rules system - the rules are clearly & plainly written with respectable/suitable art, but again it's a little too much tied to the setting provided within - players seeking a 'generic' one size fits all system to use in their own settings might be a little disappointed.
With many years of space gaming fun/experience, what I think what CBF could do with is a 'Shipyard Designers Supply Catalogue' of weapons, missiles & other systems, so that players working their own game setting can create ships to fit it.
For the rules I'd give it 4 stars as a fair representation of the system, but again it's a little too tied to the supplied setting for my needs, so bearing that in mind 3 stars is better.
