Simply put, Jim Wampler writes good stuff. Heck, he's the author of Mutant Crawl Classics, a game that DCC RPG-ified a world full of gamma radiation. See what I did there? ;)
Check This Artifact is along those lines:
Clocking in at over 56 pages and crammed with content, Check This Artifact contains 30 brand-new artifacts of the Ancient Makers, plus a brand-new godlike AI, all for use in your mutant crawling or other post-apocalyptic role playing game. Penned by the creator of Mutant Crawl Classics RPG and published by Mudpuppy Games, these powerful technological treasures are more than mere artifacts, because each item in this book is a plot hook and a potential mini-adventure in the making.
Check This Artifact presents artifacts for your players to attempt to track down, tame, and temper — including weapons, armor, robots, AIs, and those extra-special items that are the sole purview of far-future fiction. Just check out the contents page.
So, how much is the buy-in? 10 bucks for the PDF. 15 bucks for the softcover plus PDF (shipping not included). I think I'm in for the softcover :)
