I love this adventure, but I would recommend against running it out of the box. This is an adventure that benefits from some prep time; it's very much a blank slate, and any of the aspects (the kobolds, the plague, Jakk, the town itself) could benefit from some beefing up. But it's a great 12-page, 99-cent starting point to build a good adventure, and the villains (kobolds/Jakk) could easily be spun into a bigger campaign. I wrote more about running this in 5e on my blog, but overall - it's a good buy.
