This is a free / rules-lite RPG system I made. It is largely adapted from the system I designed when I played D&D (lite) with my daughters years ago.
Rules in one page For both players and the GM.
Gamemaster Guide Additional notes on game mechanics, adventure design, and some sample monsters & traps.
Printable sample characters These are formatted such that if you print on both sides of a page, you'll have the character sheet on one side and a brief rules synposis on the other side.
