In the not so distant future, mankind has finally decided to spread beyond the boundaries of our world. The United Nations is giving out subsidies to any corporation who will invest time and money into the terraforming of the great red planet. 

In Terraforming Mars Ares Expedition: Crisis, players will play as corporations, just as in the original Ares Expedition. You choose phases and play project cards as normal. The difference is players are working together to keep Mars habitable after a natural disaster has landed the planet in crisis.

Terraforming Mars Ares Expedition: Discovery adds four new mechanics to base Ares Expedition: awards, milestones, upgraded phase cards, and wild tags.

Awards are end-of-game scoring that are granted to the player with the most of something. Three awards are drawn at the beginning of the game so that players know what they will be rewarded for at the end of the game. The player with the most of that item earns 5VP, second place earns 2VP.

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.

Turmoil, the fifth expansion to Terraforming Mars, takes players back to Mars, and the struggle for control and progress of human society on a big and dangerous planet.

The expansion includes new corporations, new projects, and a new type of cards — Global Events, from dust storms to riots to rising alloy demand — that give you something to plan for 3 generations in advance.

Terraforming Mars: Colonies

Our world has widened before us. Corporations expand their operations to all corners of the solar system in pursuit of minerals and resources. Most places are not suited for terraforming, but building colonies may greatly improve your income and your possibilities in achieving that higher goal — the terraforming of Mars. Send your trade fleet to distant moons! Colonize the clouds of Jupiter! And let your Earth assets propel you to success!

Porta Nigra

The largest Roman city north of the Alps in the late Roman Empire was Augusta Treverorum. Founded in the times of Caesar Augustus and built up by generations of Roman architects, this was the Emperor's residence and a world city during this period. The remains of these most impressive structures can still be visited today. Foremost of these great achievements in the city is the massive "Porta Nigra", a large Roman city gate located in Trier, Germany that dates to the 2nd century.

Welcome to the height of technology and comfort, the Space Station Atlantis! All the comfort of a five star hotel, mixed with the adventure of space travel.

Diamonds 

Diamonds is a trick-taking card game in which players collect Diamonds — not cards bearing that suit, mind you, but rather actual "Diamond Crystals" (acrylic crystals) included in the game.
