Old School Hack, Basic Version

Publisher's blurb & user summary: Old School Hack is a table-top roleplaying system that's a hack of a hack of the original Red Box version of a certain popular hack-and-slash fantasy game. That's a lot of hacking. Old School Hack is a hack inspired by Basic D&D, Storming the Wizard's Tower, Lady Blackbird, and most notably Red Box Hack. Red Box Hack in turn is a sort of a reimagining of Basic D&D, only with some story-game elements and set in a more wuxia asian-themed world. Like D&D it has levels, hit points, and classes, and XP is gained through killing monsters and getting treasure. It's simplified quite a bit, and is extremely and entertainingly pick-up-and-playable.
