| Best For | Groups who want long-form science-fantasy campaigns that move from a ruined Earth to other dimensions. The game suits tables whose GM will decide which parts of the broad setting a campaign uses. | Sandbox fantasy campaigns with deep worldbuilding tools, faction turns, and an OSR-flavored system from the creator of Stars Without Number. |
| Highlights | Occupational and racial class packages assign distinct abilities and advancement tracks, giving each archetype a different role in the party. Mega-Damage places many supernatural creatures and war machines on a separate durability scale beyond the reach of ordinary Structural Damage Capacity attacks. Rifts and ley lines make dimensional travel a standing feature of the setting, letting campaigns move between devastated Earth and other worlds. | Free version is very generous, comprehensive sandbox and worldbuilding tools, faction system, compatible with SWN |
| Considerations | Character creation combines rolled attributes with extensive skill selection, making first-time preparation lengthy. Combat asks each player to track an action economy, active defenses, and which damage scale applies. Magic and psionics use separate point pools and power procedures, adding class-specific rules to the shared system. | OSR combat can feel basic compared to modern tactical systems, limited mechanical support for narrative or story-arc campaigns, no built-in social encounter system |
