While this is my favorite RPG Ruleset of all time, the scan suffers from a few major issues:
1) the inside cover map is unreadable at the DPI used in scanning it.
2) there are missing pages (2 of them, one of which has content of an introductory nature, the other has no significant content)
3) the OCR was horrid
4) The errata is neither included nor integrated (and there is QUITE a bunch of it).
It is, however, an awesome system.
I'd rate the rules a 4.9/5
I'd rate the PDF as 3/5 over all ignoring rules
I'd rate the Layout as 4/5
I'd rate the editing as a 1/5 simply due to the massive errata errors.
Also, it is important to understand that the OCR searchable text makes the original text look well edited.
