The product is good for it's descriptions: (210 approx).
Artwork is fairly good (not great, but OK).
Although it is a bit pricey for 66 pages (£7.24 over here in the UK).
It appears to be the only one of it's kind (exploring derelict starships).
Could also be used for space stations, colonies, etc (with a little work).
I'm not saying it's bad; it is good, but it could have been cheaper for its 66 pages.
I would have given it 5/5 if it were cheaper, or had more content.
[4 of 5 Stars!]
