Description
Self-Sustaining Arcologies joins closed urban ecologies to megastructure-grade construction. It is an optional synthesis between Industrial Megastructure Empire and Expansion and Terraforming, not a gate on either capstone.
Benefits
Housing capacity Empire-wide+4%
Strategy notes
Self-Sustaining Arcologies develops the Production discipline within Cross-Path Synthesis. This synthesis combines Industrial Megastructure Empire with Expansion and Terraforming without replacing either core path. Its immediate value is +4% housing capacity. The principal counterpressure is that cross-path investment delays a focused capstone and exposes two different resource dependencies.
Player hints
This is a specialization milestone. Reaching it reveals stronger combinations, but broad tier-three investment will slow every capstone. Favor this technology when its Production benefits reinforce your current economy, fleets, or frontier. Pause the branch if its expected RP per tick is too diluted or its resource costs would stall higher-priority projects.
