How to choose characteristics for Star Psychic Ascension?

Choose mechanical ascension

Mechanical ascension is good. Don’t eat apples. Double slots to increase the population and ignore the livability penalty. The Mechanical Empire ascension route is different from the three major ascension routes. The Mechanical Empire has its own exclusive ascension to the Machine Age and the Synthetic Era, both of which require unlocking two other ascensions (and require specific technologies) before they can be chosen.

"Mechanical World" unlocks new landform transformation options, which can transform any habitable planet into a mechanical planet. The "Synthetic Age" provides additional modification points and reduces modification costs.
