Them Deeper Bones?
Them Deeper Bones is a retro adventure role-playing game in the vein of the BECMI (“Red Box”) D&D and AD&D 2nd Edition. In TDB adventuring heroes set out to explore the post-post-apocalyptic fantasy world and piece out the history of their lost homeland. If you like to solve problems through your own wits and role-playing instead of dice-rolling and character optimisation, this is the TTRPG for you.
Some key features:
- Role-playing as the primary problem solving tool. Think using your wits in escape rooms, but where the sky’s the limit on how strange the puzzles can get.
- Streamlined d20-based system - of summing up dice with the base d20 instead of static bonus and penalty mathematics.
- Emphasis on the exploration and archeology parts of dungeon crawling, with treasure serving as a tool, not the end purpose.
- Magic system that allows individual spells to be both relevant and unpredictable.
- Tense and fast-paced combat system. The players have all the information they need to act thanks to the decide first initiative, things escalate quickly and the innovative Grit Dice method used stops it from ever becoming a grind.
- Group-focused play - through the Rediscovery Company framework that makes developing and investing in the whole group as important as individual characters in it
