This book follows in the tradion of the original TSR Underworld and Wilderness Adventures. This game utilizes Swords and Wizardry White Box Edition rules and converts the game from European fantasy mashup to Golden Age comics and depression era pulp fiction. Scott Casper has cleverly reworked those tried and true rules to back his 4 color world. If you are looking for a more "realistic" and crunch worthy superhero game this may not be to your taste. If you love old school retroclones and want a simpler game that almost anyone can learn within minutes this is a slam dunk. I am personally using this system to power my (prepare for another product plug-also available on Drive Thru RPG) Weird Adventures campaign. It is system neutral and a perfect fit. It would also fit a level based, dungeon crawl game set in this era. I would love a tad more polish (see my other reviews on the previous two books) but this pay version is the only one available currently. Give it a spin.
