CREATE LIFE ON MARS Lead a corporation and launch ambitious Mars terraforming projects. Direct massive construction works, manage and use your resources, create cities, forests and oceans, and set rewards and objectives to win the game! In Terraforming Mars, place your cards on the board and use them wisely: - Achieve a high Terraform Rating, by increasing the temperature and oxygen level or creating oceans... Make the planet habitable for future generations! - Get Victory Points by building cities, infrastructure and other ambitious projects. - But watch out! Rival corporations will try to slow you down... That's a nice forest you planted there... It'd be a shame if an asteroid crashed right on it. Will you be able to lead humanity into a new era?

From the Southern Wilds to the Other Face of Mars, the taming of the Red Planet continues. • Add the Venus board to your game, with a new Solar phase to hasten your games.

Verdict
The clearest difference is review sentiment: Quad Clock at 100% against Terraforming Mars's 45%. Quad Clock also leads on price (Free vs $8.99) and rating (5.0 vs 4.5). Terraforming Mars's advantage is ratings volume (7.5K vs 1) and update cadence (every 3 weeks vs every 2 months). On ads and device support there is nothing between them.
