Chronologically MC2 takes place before the establishment of United Earth in My Colony universe, according to the background settings set by @bastecklein.
Things might be less complicated than in the era taking place in My Colony (classic).
Roughly thinking, I guess we can have story campaigns in MC2.
And because it might be before the Earth Unification War, there are still independent nations. This means... A space race might occur. There might be different nations or alliances having their own special technologies.
If you are asking for more detailed items, here they are.
- <FutureTech Alliance>
The alliance of of the Western advances, directed by United States and the European Union. Owning the majority of world's capital and state-of-the-art talents, the Alliance pioneered the space colonization era.
- <Red Satellites Treaty Union>
RSTU, better known as ‘Red Union’ , the Union was formed under the influence of old Eastern powers Russia and China in order to rival the FutureTech Alliance. Their unmatched mass-production capabilities and highly developed cyber technologies are their strong foundations of space race.
- <Brotherhood of Polaris>
The third-world nations had been kept being neglected by the rest of the world. Instead of waiting being saved from unfairness and despair, they decided to fight for themselves. The Brotherhood had the connection to a mythical, religious organization, which the organization assisted them by fostering unification and supplying them resources needed for confronting the powerful rivals of space race, to ultimately discover the promised land they desired. Their strong faith brings them courage and endurance to overcome any difficulties.
- <Project SEED>
While other alliances seeks for power and wealth in the space race, only few people still put the importance on continuation of species - Which, the space race further catalysing the irreversible catastrophe of ecosystems. What Project SEED seeks for is a place to save remaining species on Earth from, meaningless competitions that will only bring calamity to everything.
- New City of Prosperity
The race between FutureTech Alliance and RSTU. At the late stage both factions found themselves stepping into the ecosystem calamity they had created on Earth, eventually cutting all assistances to the colonies, and abandoning all of them in the loniness... Which the colonies must survive from.
- The Exodus
The story of the Brotherhood finding their promised lands. The beginning was smoother than expected, however internal conflicts of the Brotherhood were incubating in the shadows, the colony must made the best choice in this crisis.
- The Ark of Life
The attempt of Project SEED creating a new Eden for species on Earth. The terraforming gave them tough times, failures from other SEED colonies had aroused suspicion of colleagues, however all these would lead to the discovery to save Earth from the ecosystem calamity.
