Martin, you mentioned on the news side that the D100 Space book/pdf is being updated at the same time as the Galaxy Builder is being validated.
Are there major changes in the D100 Space book? In order words, for those of us who already own D100 Space and will be getting the Galaxy Builder when it is ready, is there an issue using the two together requiring us to have to get a new D100 Space book?
The news article points to the download page and an errata pdf for D100 Space. The errata details all the changes that need to be made in the printed book. The D100 Space pdf will be updated when everything is validated by the printer and hard copy proofs have been received and checked for sale. You will get a notification via email of the pdf when it goes live and you can download the new version from your library. The most notable change is to the space combat table.
