It's definitely worth the 99 cents they're charging. It's got a handful of things in each of the categories they listed, and most are interesting enough--some are directly derivative from prior games' monster manuals and adventures. There is no art, and a hand-drawn map. The map is interesting in that the scale is "days on foot" which would be a pretty cool concept, but for the face that the map doesn't actually reflect that. Based on historical travel you'd create some interesting maps using a scale like that, with most civilization clustered really close together, and things like mountains and dense forest would spread out and occupy an inordinate amount of space. Don't get me wrong, the map still functions, but it's weird that it takes the same amount of "time" to travel between a city and a village as it does to cross a mountain range (without a trail or pass!). The cartographer in me went, "woah, this would've been so cool if it was done right!"

Anyway, worth the purchase, there's good stuff here that a GM could literally skim for 15 minutes and run a few games just from that...if that ain't worth a buck, what is?

This fits in surprisingly well with the Plague of Storms supplement for Dungeon World which I am really enjoying.

Well, it's worth a buck. 12 pages with moves, ideas, magical objects, monsters etc. Not 100% fresh and original, still well done, following all the Dungeon World rules (ie. the steadings have all their tags etc.).
