There's some content cut out. In Purgatory, the d100 encounters and Karpyl Bridge aren't in the zine (and maybe something I'm forgetting, but pretty sure that's it). Most of the cut content ended up in the Refuse zine though (here)!

I think almost everything cut is in Refuse besides a few encounters. I whittled it down from d100 (overland and city) encounters to d88. But I also gave everything a once-over. So that at the end of the day, the people who have the original hardcovers still have some special things and not just an inferior version (but it being a hardcover in of itself is also a plus I guess). :)
