Let me start by saying that the Black Hack has been a great addition to the OSR landscape. A ton of settings to add to a simple and versatile system. The Jack Hack is by far my favorite of those. Late Victorian roleplaying dealing mostly with the seedy, criminal side of life. You play a desperate person, fallen on hard times and barely hanging on. All this against the backdrop of the Jack the Ripper murders. The unique usage dice of the white and black help to flesh out what a character was before their fall from grace and what contributed to their fall. It is gritty, street level play and very challenging the more detail you add (just look up the Victorian era legal system and range of punishments). The random tables, use of era appropriate slang and story hooks are terrific. My quibbles are small but I feel they keep this product just great and not fantastic. This REALLY needs a some editing. Numerous typos and mistakes are distracting. Some basic information about social mores, standard prices and definitions of the said slang would be really helpful for us on the other side of the pond. Granted one could find this elsewhere but having it here in an abbreviated form would be easier. That said this product is awesome and reasonably priced. With a little more polish this would be five stars easily. Also finish Dead London...please!
