Natural 20

Natural 20, or n20, is a role-playing game system that bridges the gap between board games and role-playing games. The design goal was to develop a fast, action-packed, and above all else, a fun to play system, that has all the flexibility and freedoms of a traditional role-playing game while still keeping the rules and other game components as compact and easily accessible as a normal board game.

The rules are constantly play-tested and updated. The complete rules can be found in n20 Wiki.

What n20 brings to the table

  • Compact yet comprehensive combat rules for a fast and fun gaming experience.
  • Combines traditional d20 mechanics with a novel die rolling system to keep unnecessary math to the minimum.
  • Easy and fast, yet flexible and versatile character creation.
  • Team dynamics system that gets everyone involved in the game and prevents individual players from dominating the events.
  • Storyline rules for a natural flow of events with minimum record keeping.
