| Best For | Groups who want gritty, tactical, and realistic combat in a skill-based percentile system, particularly for historical, mythic, or low-fantasy settings. | Hard sci-fi sandbox campaigns with trading, exploration, and realistic space travel. |
| Highlights | Tactical Special Effects combat system, classless skill-based progression, five distinct magic systems, adaptable to many genres, free intro version (Mythras Imperative) | Comprehensive sci-fi toolkit, lifepath character creation, detailed trade/travel systems |
| Considerations | Steep learning curve for combat, analysis paralysis when choosing effects, large combats become unwieldy, lengthy character creation | Lifepath character creation rolls for aging and career mishaps, so a Traveller can leave chargen weakened or pushed onto an unwanted path. Subsystem rules are spread across multiple supplements, so the core book leaves several procedures without full depth. Characteristics are recorded as a hexadecimal Universal Personality Profile string, an unusual notation newcomers must learn before they can read a stat block. |
