[X] (A.I Leadership) Close the distance to broadcast the activation signal…
[X] Land in the moon
[X] Oceanus (Planet) & Pindar (Moon)
Seeing as we're naming the system after the Greek perception of the afterlife, might as well name the celestial bodies after people and landmarks within or related to it. Oceanus is the Titan God of the Oceanus River, which was said to envelop the entirety of the world, while Pindar was a great philosopher who wrote about Elysium.
As for the actual choices themselves, I decided to go for the AI leadership option since it offers the most benefits for the least cost; while it might not succeed, it would not risk punting Mario-1 into the sun, and would provide some valuable experience for the AI regardless of success. Our colony location is a more complicated choice, especially considering how habitable Elysium-3 is. I would say building a space station would be a poor choice; of course there's the drawbacks presented within the turn itself (expensive to build in comparison with the materials we have, cramped living spaces etc.), but also take into account that in open space it would be easier for a meteorite or other object to crash into the colony (moon might have some form of natural caverns to build inside of, planet has a atmosphere which would vaporize any insignificant debris). The planet is quite tempting, but I would also pass on settling there for now, considering that we know little about the planet itself aside from the obvious.
