Cards have dual roles in both games
Dune cards can be used for Agent placement or saved for Reveal effects, persuasion and combat strength. Arnak cards can provide effects and travel icons, linking your deck directly to board access.
Dune is more interactive
Conflict rewards, faction Alliances and scarce board spaces create direct competition. Players constantly evaluate whether opponents are committing troops or preserving strength.
Arnak is more about conversion efficiency
Exploration creates new worker spaces and Guardians; research converts resources into track progress and temple scoring. The challenge is squeezing value from a limited number of actions over five rounds.
Deck building feels different
Dune’s Imperium Row emphasizes card synergy, Agent icons and reveal effects. Arnak decks are smaller and cycle more slowly, so each acquired Item or Artifact can have a strong effect on travel and resource planning.
Expansion direction
Dune expands through systems such as Tech, dreadnoughts, Tleilaxu research, commanders and new Leaders. Arnak expands through asymmetric leaders, campaign content, alternative research tracks and new maps/cards.
Which fits your group?
- Dune: Imperium: better for higher interaction, conflict and political/faction pressure.
- Lost Ruins of Arnak: better for a less confrontational efficiency puzzle with exploration and research.
