This review applies to the recently updated version of the PDF.
The First Steps book contains a wealth of original material for the SG-1 game, ten new worlds to explore each described in detail. There are new alien and near-human races, new skills and new feats to go with these worlds.
The PDF is a scanned image of the book, rather than a publication created from the original typesetting material. The image format results in a large file size.
The tracking lines, evident in the previous version available here, have now gone. The image quality is much better than the previous version as well. The missing pages, pages 77 and 80, have made it in to the new scan.
A much better version of the PDF making this a good purchase for the SG-1 game.
