| Core Mechanic | The GM rates each task from 1 to 10 and multiplies that difficulty by 3 to set the target number. Players roll a d20 and succeed on a result equal to or above the target. Skills, assets, and Effort ease the task before the roll, with Effort paid from the relevant stat Pool after Edge reduces the cost. | Roll d20 + skill bonus + attribute bonus. A result of 1–9 fails with a complication, 10–14 succeeds at a cost, 15–19 fully succeeds, and 20+ succeeds with an epic effect. |

| Best For | Groups building genre-spanning campaigns who want broad character customization, player-facing resource decisions, and little mechanical preparation for the GM. | Groups seeking a two-hour, genre-flexible one-shot where the same d20 engine handles action and conversation. |
| Highlights | Player-only rolls keep the GM focused on adjudication and scene management. Descriptor, type, and focus choices support broad customization across multiple genres. One-use cyphers continually rotate situational abilities through play. | The same d20 roll handles standard checks and direct contests, making transitions between scene types quick. Interface scales open-ended supernatural or technical effects by skill tier, letting one procedure cover magic and hacking. NPCs need a core bonus, Strikes, and an optional trait, so a GM can prepare threats with few statistics. |
| Considerations | Players manage Pool spending for abilities and Effort, so pushing a roll competes with other resource uses. Abstract distances and level-based NPCs leave many tactical details to table rulings rather than map procedures. The broad toolkit asks the GM to select genre modules and character options before play. | No default setting is provided, so groups must supply a world for their adventure. Gear grants fictional permission rather than numeric bonuses, limiting equipment-based builds. Strikes reset after each adventure, so the track does not preserve mechanical attrition between adventures. |
