From publisher blurb:
Wonderland Imprints is proud to present the Oldskull Game Expansion series, providing exciting and inspirational materials for players and Game Masters who prefer to play the Original (OSR), First Edition (1E), and Second Edition (2E) versions of the world’s greatest role-playing game. If you’re looking for universal and directly compatible old school materials to bridge the original game editions created by Arneson and Gygax (1974-1985), Holmes (1977), Moldvay and Cook (1981), Mentzer (1983-1986), and other luminaries of TSR (1974-1989), you’ve come to the right place. Players of Fifth Edition will also discover much of resourceful interest here, because these historically-informed systems are rules-light and concept-heavy, ready for quick conversion to the ruleset of your choice.
This unique modular compendium of optional rules, elaborations, and clarifications will give you the tools to bridge the Basic, Expert, and Advanced game series with codified and interrelated structures, each designed to inspire you and to enhance any Player Character you’d ever like to create.
Herein you’ll find nearly 120 easy-to-use tables, each designed to add creative options, inspirations, exciting new ideas, and ease-of-play aids without adding significant amounts of in-game complexity. And best of all, the rules and systems provided throughout this supplement are fully optional, interfacing directly into the existing old school Basic / Expert system as pieces to a larger puzzle. Choose all of the pieces you want to use in the here and now, and set the rest aside for a later time.
