Kabuki Kaiser are running a 10-day sale on their digital products on DriveThruRPG [AL] and RPGNow [AL] as the company moves east across the country. This sale applies to both the Mad Monks of Kwantoom [AL], and the Ruins of the Undercity [AL], both of which are excellent products which defy being placed into just one category. Each of them provides lots of setting content that can be used for normal group play, add a lot of extra content and usage beyond that and allows for solo play for when you can’t get a group together to play. Although set up for use with Labyrinth Lord, you can easily use this with many other OSR systems.
Update: This has been extended for two days more, and will end on Sunday Jul 20th, 2014.
