The system is managed all at once, and the planets are only important as vessels for pop units, being restricted by habitability, and separated by resource production rates. The main unit of space is a system, which houses planets. Other than that, the gameplay in Endless Space 2 is relatively simple. You’ll see the leaders of other races in the diplomacy screen.
However, the Vodyani are also energy vampires and they need to draw Essence from other races to construct their population units and Arks. Much like barbarian camps in Total War: Attila, they harbor all of the planetary improvements and can easily transport them from system to system. Meanwhile, the Vodyani, who religiously worship the Virtual Endless, don't colonize planets as much as subjugate systems with their Arks. If that ship remains undisturbed for 10 turns, you can immediately colonize the system, which makes the spread of the Unfallen very slow and methodical. Instead, they send a ship to neighboring system to plant a beacon for interstellar vines. Unfallen, ents in space, don't have colonizer vessels. United Empire, a hegemony both corporate and feudal, can have the Emperor flex his muscle and hasten not only build times, but even research by spending the influence resource, making UE the race most interested in its generation. Unless they don't: while all races have their own quirks and gameplay differences, some are more different than others. Chosen from a number of different species, they all start their trek to the stars in a single system, having already built a scout ship and a colonization vessel. But that's not a question many care about, and it certainly isn't something that will impede your space empires. I always wondered how these precursor races always leave behind ruin-strewn worlds that mysteriously aren’t stripped of all mineral wealth. Results are carefully monitored, however, and as mechanical control of the "Cloth" worn by every Vodyani is in the hands of the Church, there is little room for independent thought, much less rebellion.Space is beautiful. Prayer, recitation, and study are important parts of everyday life, and as study involves ruins, relics, and ancient technology much of their religious activity has pragmatic consequences. As they were saved from extinction by the technology of the Virtual Endless, it is only natural that they in turn worship these all-powerful precursors as gods. Vodyani society is organized as a formal and hierarchical church that worships the Virtual branch of the Endless.
Though their civilization has become tied to their great starfaring Arks, Tchinomy remains a powerful symbol both as a lesson in ecology and as a memory of the weak and grotesque forms the Vodyani had before Virtual technology allowed them to evolve beyond that. As a result, the Vodyani were driven into space by necessity and already have a long history as a ship-bound people. Tchinomy, the home planet of the Vodyani, was a poor yet temperate world, and the fragility of its environment meant it was soon depleted. She is also famous for her brother - the heretic Isyander Shumèd, who nearly destroyed the society when he led a revolt against his own people. The current hierarch is Isyara St Shaiad, famous for her rigor and intensity. This person, drawn from one of the powerful organizations that make up Vodyani society, is the ultimate authority for both religious and secular affairs. While there are many sprawling departments and executives within the Church of the Virtual Saints to handle the functions of running a starfaring civilization, there is only one ultimate authority - the Hierarch. Clothed in their great black suits of borrowed technology, Vodyani leaders pilot their great Arks across the star lanes, seeking other peoples to convert, control, and consume. These precursors quickly gained an aura of divinity in the eyes of the Vodyani, and are now worshiped as gods. Victims of a classic cycle of over-industrialization, the Vodyani were saved by technology culled from ruins of the Virtual Endless.
