United States Race the Stars (discontinued)

It is the 23rd century. Earth has suffered a great catastrophic war that caused massive damage to it's eco system and destroyed many smaller and weaker nations. The larger much more stronger nations that survived and adapted were able to ascend into space, colonizing other systems into their rule and ideologies. While no conflict is allowed on earth, these nation still compete and align themselves with each other through out the cosmos. However an energy signal has been detected in deep space, leading the space faring human nations to prepare expeditions of their own to locate and retrieve the signal. This space race, may be the key to uniting the separate human nations, but under who's influence is yet to be decided.
