I purchased this pdf so I could keep my print copy from falling apart. The pdf quality, apart from the slightly poor quality scan of the covers, is excellent with crisp text and interior art. The original fold out Chicago city map is also reproduced as an electronic version which is nice and easily printable for gaming use.
While this sourcebook book was originally for Shadowrun's second edition, so the mechanics contained inside are outdated for the latest 5th edition. But I can still find tons of uses for this book. The writing is atmospheric and sets the mood for the mostly destroyed Chicago like no other sourcebook written for Shadowrun. This book actually ranks probably one of the best sourcebooks ever written for the Shadowrun universe in terms of focus and style. The Bug City "sub-setting" is actually culmination of the events of a few previous adventures, like Universal Brotherhood. They're not need to run Bug City but can be combined to a wonderful long story campaign. To this day, I've run more games of Shadowrun in the Bug City than any other locale in the setting. It simply is that good.
4 out of 5 score, comes from the from the lack of print-on-demand option (at the time of writing) and the slightly poor quality scans of the covers. The setting material itself is easily five star material.
