Terraforming Mars: Core Game

In the 2400s, mankind begins to terraform the planet Mars. Giant corporations, sponsored by the World Government on Earth, initiate huge projects to raise the temperature, the oxygen level, and the ocean coverage until the environment is habitable. In Terraforming Mars, you play one of those corporations and work together in the terraforming process, but compete for getting victory points that are awarded not only for your contribution to the terraforming, but also for advancing human infrastructure throughout the solar system, and doing other commendable things.

The players acquire unique project cards (from over two hundred different ones) by buying them to their hand. The projects (cards) can represent anything from introducing plant life or animals, hurling asteroids at the surface, building cities, to mining the moons of Jupiter and establish greenhouse gas industries to heat up the atmosphere. The cards can give you immediate bonuses, as well as increasing your production of different resources. Many cards also have requirements and they become playable when the temperature, oxygen, or ocean coverage increases enough. Buying cards is costly, so there is a balance between buying cards (3 megacredits per card) and actually playing them (which can cost anything between 0 to 41 megacredits, depending on the project). Standard Projects are always available to complement your cards.

Your basic income, as well as your basic score, is based on your Terraform Rating (starting at 20), which increases every time you raise one of the three global parameters. However, your income is complemented with your production, and you also get VPs from many other sources.
