If I may suggest a series that could work for 2000 years worth of timeline:
Jerry Pournelle and Larry Niven's shared universe that culminates in the classic "Mote in God's Eye".
For those not familiar, they break into two series with one timeline.
It begins with the idea of a CoDominion--The USA and Russia basically taking over Earth as a joint venture. Faster than light is accidently discovered and they start exporting colonists--some voluntary, some involuntary--to other planets to stop the overpopulation on Earth.
As the CoDominion falls apart, mercenaries overseen by a strict code of conduct go to war for colonies fighting each other. (How strict? Violations could result in bankruptcy at best or nuclear retaliation from earth at worst)
Eventually, the CoDo falls apart, and the planet of Sparta starts an interstellar empire to secure peace.
2000 years later a second empire (the first fell) makes first contact.
The first period is great for small unit, releatively low tech games since the mercenaries use conventional firearms and almost no armored vehicles.
The Second period is great for space opera with lazer pistols and gamma-ray cannon wielding battleships against aliens with asymetric bodies and birth rate that makes rabbits blush.
