▼ marks the lower resource / time cost. Cheaper isn't always better — weigh it against the effect each tech unlocks.

Stellar Engineering

Manipulate stellar physics to stabilise rogue star systems for colonisation. Unlocks 2 additional building slots on any star-adjacent colony.

Unlocks buildings: stellar regulator

Requires: colonization 12, science 5

Megacity Planning

Arcology design and urban stacking increases maximum planetary population capacity by 40%.

Unlocks buildings: arcology district

Requires: colonization 7

Which Should You Research First?

The Megacity Planning is the lower-tier prerequisite step and typically comes first in the colonization branch, opening the path toward Stellar Engineering.
