This is a method that you can summarize on a page, uses only six-sided dice, descriptive character generation, and just two basic mechanics. And the point of this is that the rules, the "Visible Rulebook" to borrow a term from from S. John Ross, are necessary only to the extent that they facilitate the interaction between the players, their characters, and the worlds they want to explore.
Here's the method for playing the world:
1 - Characters
Briefly describe your character, including notable attributes, like skills, characteristics, or professions (maybe five or so). One or two attributes may count as outstanding (use two words for emphasis like "excellent tracker"). The necessary level of detail is to create a playable role.If you're stuck, roll dice to help you decide on your attributes, and refer to any work of fiction, rule-set or character generation system for ideas about stats and skills, professions, and backgrounds.
In general, a modifier for a notable one-word attribute is +1, an outstanding two-word attribute (skilled swordsman, talented pilot) is +2, and rare superlative attributes (exceptional swordsman; best pilot in the system) are +3.
2 - Tests
When you need to account for risk or uncertainty, roll the dice. An average roll (around 7) is average, you most likely continue but the situation is not necessarily resolved, high is good (around 9+) and usually decisive, low (around 5-) is bad and entails negative consequences.
Apply modifiers for suitable character attributes and the situation and equipment in the +3 to -3 range.
For the sake of greater flexibility, I'd suggest six hits, with stronger characters adding 1 or 2 more as indicated by a suitable attribute. Lighter attacks deal 1 hit. Heavier attacks can inflict 2 or 3 hits. The GM should apply judgement and err on the side of character survival. A character at exactly zero hits is stunned, staggered, dropped, and so on, but not dead.
Apply modifiers for suitable character attributes and the situation and equipment in the +3 to -3 range.
3 - Opposed rolls
Roll the dice for opposing efforts (such as combat, but also other cases of active opposition) and compare. Highest wins, and the bigger the difference the more decisive the outcome. Apply modifiers, as for tests.4 - Hit points
Darkworm Colt uses a "three strikes" system: character can take three hits and then they're out. Tougher characters might have more hits at the GMs discretion.For the sake of greater flexibility, I'd suggest six hits, with stronger characters adding 1 or 2 more as indicated by a suitable attribute. Lighter attacks deal 1 hit. Heavier attacks can inflict 2 or 3 hits. The GM should apply judgement and err on the side of character survival. A character at exactly zero hits is stunned, staggered, dropped, and so on, but not dead.
5 - Play the world
The game isn't in the method; the game is in the sources you choose for inspiration, in the worlds you construct, and in the scenarios the GM devises and the creativity players bring to them.
