Synthetics traditionsWhy players run Synthetic Fertility
Players' advice in our words, not the game's data — each line links to where it was said.
- Take the Synthetics traditions as the second tree: players report very high pop growth and leading every empire by year 50.[1]
- Origins that start an ascension early are what returning players are told to pick, this one for synthetic ascension.[2]
- "Synthetic Fertility Elites" is a default meta build for tech rushers; the game's own premade version is still called strong.[3][4]
- Don't pair it with a civic that cuts your starting pops: the transfer becomes a struggle.[5]
