Ark Nova vs Terraforming Mars: Which Heavy Engine Builder Fits You?
Ark Nova and Terraforming Mars are long-form card-driven engine builders where early efficiency compounds into late-game scoring. The difference is where that engine lives: Ark Nova combines a personal zoo map with shifting action cards, while Terraforming Mars builds a corporation around production tracks, projects and a shared planetary map.

Ark Nova makes action timing part of the engine
Your five action cards slide across strength positions. Using a powerful action weakens that card temporarily while strengthening the others, so sequence planning is central.
Terraforming Mars makes production timing central
Steel, titanium, plants, energy, heat and M€ production can compound over multiple generations. The shared global parameters also create a collective game clock that opponents can accelerate.
Map interaction
Ark Nova’s enclosure puzzle happens mostly on your own zoo map. Terraforming Mars uses a shared map where cities, greeneries and oceans affect placement bonuses and final scoring.
Card volume and prerequisites
Both games contain large card decks. Ark Nova cards often care about animal icons, enclosure size, reputation and partner institutions; Terraforming Mars cards often depend on tags, production, global parameters and resource discounts.
Scoring visibility
Ark Nova’s final score is determined by the relationship between your Appeal and Conservation markers after the game-end trigger. Terraforming Mars combines TR, map scoring, cards, milestones and awards.
Which fits your group?
- Ark Nova: better for players who want a strong personal-board puzzle and action sequencing.
- Terraforming Mars: better for players who enjoy production engines, a shared map and a larger expansion ecosystem.
