Terraforming Mars

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.

As a player, you acquire unique project cards (from over two hundred  different ones) by buying them to your hand. 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 and  actually playing them. Standard Projects are always available to  complement your hand of cards. Your basic income, as well as your basic  score, are based on your Terraform Rating. However, your income is  boosted by your production, and VPs are also gained from many other  sources.

You keep track of your production and resources on your player board.   The game uses six types of resources: MegaCredits, Steel, Titanium,  Plants, Energy, and Heat. On the game board, you compete for the best  places for your city tiles, ocean tiles, and greenery tiles. You also  compete for different Milestones and Awards worth many VPs. Each round  is called a generation and consists of the following phases:
