Solarii

From the designer's website:

"'Time Mark 10487: The discovery of the Stellarium and its tremendous energetic properties plunges the solar system Solarii into a turmoil. Long haul space travel is finally possible.

"'Time Mark 10495: Using this new technology, probes are sent throughout the Galaxy seeking new worlds. The powerfull Environmental Leagues request that the upcoming expansion doesn't interfere with the Peace Agreements amongst Solarii's Nations. They also underscore the respect of any new form of life or ecosytems encountered.

"'Time Mark 10499: The first probes are back into Solarii. The conquest of the newly discovered worlds is starting ...'

"You lead one of the Nation of Solarii. You plan the colonization of the new worlds discovered by the probes. Your goal is at the same time to be the only master of some planets, and also to share other planets with your opponents. War, politics and ecology are your tools in this difficult task. Use them skillfully to attract partners on your worlds or prevent them from being invaded.

"Solarii uses cards to solve the interactions between players and to build the board. It's a powerful system that makes every game different from the previous ones.

"This game was among the 80 semi-finalists at the 2003 edition of the Game Design Contest Of Boulogne-Billancourt in France."
